building envelope, sometimes also called thermal envelope or building enclosure, controls the flows of between the interior and exterior of the building?
The building envelope is an essential component of any structure, providing a protective barrier between the interior and exterior of the building. By controlling the flow of air, moisture, and heat, the building envelope ensures the indoor air quality and energy efficiency of the building.
The components of the building envelope include the walls, roofs, windows, doors, and foundation of the building, as well as insulation and other materials. The primary purpose of the building envelope is to provide a protective barrier against the elements, ensuring the interior of the building is insulated from the outside climate. The building envelope also helps to maintain indoor air quality, as it reduces the amount of air infiltration from outside. In addition, the building envelope increases the efficiency of the building’s heating and cooling systems, reducing energy consumption and costs.
In order to maintain its protective barrier, the building envelope must be constructed with durable and weather-resistant materials. Additionally, the building envelope should be properly sealed to reduce air leakage. Windows and doors should be designed to minimize the risk of water infiltration, while insulation should be installed to reduce heat transfer.

A simple ideal Rankine cycle which uses water as the working fluid operates its condenser at 408C and its boiler at 3008C. Calculate the work produced by the turbine, the heat supplied in the boiler, and the thermal efficiency of this cycle when the steam enters the turbine without any superheating
Answer:
871.8008 KJ/kg
2573.42085 KJ/kg
0.3743
Explanation:
Solution:-
- We are to analyze an ideal Rankine cycle, where the condenser and boiler operating temperatures are defined.
- We start of by evaluating the properties of water at each state before and after the process.
State 1: Condenser Exit / Pump Inlet
T1 = 40°C ---> P1,sat = 7.3851 KPa , v1 = vf = 0.001008 m^3/kg
sat liquid h1 = hf = 167.53 KJ/kg , s1 = sf = 0.5724 KJ/kg.K
P1 = condenser pressure
State 2: Pump Exit / Boiler Inlet
P2 = P3 = Psat,300°C = 8587.9 KPa
Process 1: " Isentropic Compression - constant volume "
The work done by pump in the compression process is:
wp = v1* ( P2 - P1 )
wp = ( 0.001008 ) * ( 8587.9 - 7.3851 )
wp = 8.64915 KJ /kg
Determine the enthalpy at " State 2 " by energy balance on pump ( control Volume) :
h2 = h1 + wp
h2 = 167.53 + 8.64915
h2 = 176.17915 KJ/kg
State 3: Boiler Exit / Turbine Inlet
T1 = 300°C ---> P3,sat = 8587.9 KPa
sat vapor h3 = hg = 2749.6 KJ/kg , s3 = sg = 5.7059 KJ/kg.K
P3 = Boiler pressure
Process 2: " Heat Addition - constant pressure "
The heat supplied in the boiler is:
qb = h3 - h2
qp = ( 2749.6 - 176.17915 )
qb = 2573.42085 KJ /kg .... Answer ( b )
State 4: Turbine Exit / Condenser Inlet ( Isentropic )
P4 = P1 = 7.3851 KPa ..... sfg = 7.685 KJ/kg.K
s4 = s3 = 5.7059 KJ/kg.K sf = 0.5716994 KJ/kg.K
hf = 170.32524 KJ/kg
hfg = 2406.11 KJ/kg
Process 3: Isentropic Expansion - Determine the quality of liquid-vapor mixture phase ( x ) at state (4):
x = (s4 - sf) / sfg
x = (5.7059 - 0.5716994) / 7.685
x = 0.66808
h4 = hf + x*hfg
h4 = 170.32524 + 0.66808*2406.11
h4 = 1777.79920 KJ/kg
- The work-done by the turbine in the isentropic expansion process ( wt ) is:
wt = h3 - h4
wt = 2749.6 - 1777.7992
wt = 971.8008 KJ/kg ... Answer ( a )
- To determine the thermal efficiency ( nth ) of the rankine cycle. We need to determined the net work produced by the cycle ( wn ). The net work is the energy balance between the isentropic compression ( work done - pump ) and isentropic expansion ( work produced - turbine ):
wn = wt - wp
wn = 971.8008 - 8.64915
wn = 963.15165 KJ/kg
- The thermal efficiency of a power cycle is the ratio of net work-produced ( wn ) and the heat supplied to the working fluid in the boiler ( qb ) as follows:
nth = wn / qb
nth = 963.15165 / 2573.42085
nth = 0.3743 ..... Answer ( c )

State three types of maintenance.
Answer:
Tradicionalmente, se han distinguido 5 tipos de mantenimiento, que se diferencian entre sí por el carácter de las tareas que incluyen:
Explanation:
Mantenimiento Correctivo: Es el conjunto de tareas destinadas a corregir los defectos que se van presentando en los distintos equipos y que son comunicados al departamento de mantenimiento por los usuarios de los mismos.
Mantenimiento Preventivo: Es el mantenimiento que tiene por misión mantener un nivel de servicio determinado en los equipos, programando las intervencions de sus puntos vulnerables en el momento más oportuno. Suele tener un carácter sistemático, es decir, se interviene aunque el equipo no haya dado ningún síntoma de tener un problema.
Mantenimiento Predictivo: Es el que persigue conocer e informar permanentemente del estado y operatividad de las instalaciones mediante el conocimiento de los valores de determinadas variables, representativas de tal estado y operatividad. Para aplicar este mantenimiento, es necesario identificar variables físicas (temperatura, vibración, consumo de energía, etc.) cuya variación sea indicativa de problemas que puedan estar apareciendo en el equipo. Es el tipo de mantenimiento más tecnológico, pues requiere de medios técnicos avanzados, y en ocasiones, de fuertes conocimientos matemáticos, físicos y/o técnicos.
Mantenimiento Cero Horas (Overhaul): Es el conjunto de tareas cuyo objetivo es revisar los equipos a intervalos programados bien antes de que aparezca ningún fallo, bien cuando la fiabilidad del equipo ha disminuido apreciablemente de manera que resulta arriesgado hacer previsiones sobre su capacidad productiva. Dicha revisión consiste en dejar el equipo a Cero horas de funcionamiento, es decir, como si el equipo fuera nuevo. En estas revisiones se sustituyen o se reparan todos los elementos sometidos a desgaste. Se pretende asegurar, con gran probabilidad un tiempo de buen funcionamiento fijado de antemano.
Mantenimiento En Uso: es el mantenimiento básico de un equipo realizado por los usuarios del mismo. Consiste en una serie de tareas elementales (tomas de datos, inspecciones visuales, limpieza, lubricación, reapriete de tornillos) para las que no es necesario una gran formación, sino tal solo un entrenamiento breve. Este tipo de mantenimiento es la base del TPM (Total Productive Maintenance, Mantenimiento Productivo Total).

In the fully developed region of flow in a circular pipe, does the velocity profile change in the flow direction?
Answer:
No, the velocity profile does not change in the flow direction.
Explanation:
In a fluid flow in a circular pipe, the boundary layer thickness increases in the direction of flow, until it reaches the center of the pipe, and fill the whole pipe. If the density, and other properties of the fluid does not change either by heating or cooling of the pipe, then the velocity profile downstream becomes fully developed, and constant, and does not change in the direction of flow.

D5-1: A commercial airliner cruises at 40,000 feet at a Mach number of 0.78. a) What is the airliner's speed? b) What stagnation pressure do you expect on the nose of the aircraft? c) What stagnation temperature do you expect on the nose of the aircraft? Use standard atmospheric properties from Table C.1.
For a commercial airliner cruising at 40,000 feet with a Mach number of 0.78, we can calculate the airliner's speed, stagnation pressure on the nose of the aircraft, and stagnation temperature on the nose of the aircraft using standard atmospheric properties.
These values can be obtained from Table C.1. a) To calculate the airliner's speed, we need to use the relation between Mach number (M) and the speed of sound (a). The speed of sound depends on the temperature of the air at the cruising altitude. Using standard atmospheric properties from Table C.1, we can determine the temperature and then calculate the speed of sound. Multiplying the speed of sound by the Mach number will give us the airliner's speed. b) The stagnation pressure on the nose of the aircraft can be determined using the concept of total pressure. Total pressure, also known as stagnation pressure, is the sum of the static pressure (ambient pressure) and the dynamic pressure (caused by the motion of the aircraft). Using the standard atmospheric properties from Table C.1, we can obtain the static pressure at 40,000 feet and then calculate the total pressure on the nose of the aircraft. c) Similarly, the stagnation temperature on the nose of the aircraft can be determined using the concept of total temperature.

What is the maximum number of points a player can score during a frame of snooker while curving around at a 45 degree angle going at a speed of 2 miles per hour with the wind speed of 2 mph on a rug coated snooker table?
In snooker, the maximum number of points that can be scored during a single frame is 147. This is achieved by potting all 15 red balls, each worth 1 point, and subsequently potting the colored balls in sequence: yellow (2 points), green (3 points), brown (4 points), blue (5 points), pink (6 points), and black (7 points). Each color is then returned to its original position and can be potted again for additional points.
The angle and wind speed mentioned in your question are not relevant to determining the maximum number of points in a snooker frame. The speed and direction of the balls are controlled by the player's shots, and the rug coating on the table doesn't affect the scoring.
So, regardless of the angle, wind speed, or table surface, the maximum number of points that can be scored in a frame of snooker is 147.

The two structural members, one of which is in tension and the other in compression, exert the indicated forces on joint o. determine the magnitude r of the resultant r of the two forces and the angle θ which r makes with the positive x axis (measured counterclockwise from the x axis).
The liquid-phase reaction A + B → C follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of A and B feed streams are 2 M before mixing. The volumetric flow rate of each stream is 5 dm3 /min and the entering temperature is 300 K. The streams are mixed immediately before entering. Two reactors are available: One is a gray 200.0 dm3 CSTR that can be heated to 77°C or cooled to 0°C, and the other is a white 800.0 dm3 PFR operated at 300 K that cannot be heated or cooled but can be painted red or black. (Note: k = 0.07 dm3 /mol*min at 300 K and E = 20 kcal/mol.) How long would it take to achieve 90% conversion in a 200 dm3 batch reactor with CA ° = CB ° = 1 ???? after mixing at a temperature of 70°C?
Answer:
1.887 minutes
Explanation:
We are given k = 0.07 dm3 /mol*min at 300 K and E = 20 kcal/mol = 20000 cal/mol
To solve this, first of all let's calculate the rate constant(k);
For this question, The formula is;
K(t) = k(300K) × exp[(E/R)((1/300) - (1/T2))]
R is gas constant = 1.987 cal/mol.K
For temperature of 70°C which is = 70 + 273K = 343K, we have;
K(343) = 0.07 × exp[(20000/1.987)((1/300) - (1/343))]
K(343) = 4.7 dm³/mol.min
The design equation is;
dX/dt = -(rA/C_Ao) = K•(C_Ao)²•(1 - X)²/(C_Ao) = (KC_Ao)(1 - X)²
Since there is no change in volume by cause of the state at which the reaction is carried out, that is liquid. Thus, integrating and solving for time for a 90% conversion we obtain;
(0.9,0)∫dX/(1 - X)².dX = (KC_Ao)((t, 0)∫dt
So, we'll get;
0.9/(1 - 0.9) = 4.77 × 1 × t
t = 9/4.77
t = 1.887 minutes

Which type of structure is usually found under grass sod? Platy Blocky Prismatic Granular
Out of Platy Blocky Prismatic Granular, the type of structure usually found under grass sod is platy structure.
Soil structure refers to the arrangement of soil particles into aggregates or clumps. It is an essential characteristic of soil that affects its fertility, drainage, and root penetration. Various types of soil structures can exist, including platy, blocky, prismatic, and granular.
Platy structure is characterized by thin, flat layers or plates that are horizontally oriented. This structure is commonly found in compacted or poorly drained soils. The flat plates inhibit water infiltration and root development, making it less favorable for plant growth. Platy structure can result from compaction due to heavy foot traffic or the use of heavy machinery.
On the other hand, blocky, prismatic, and granular structures are more desirable for healthy plant growth. Blocky structure consists of irregular, block-like aggregates, while prismatic structure forms vertically elongated columns or columns with flat tops. Granular structure is characterized by the formation of small, rounded aggregates. These structures promote better water movement, root penetration, and nutrient exchange within the soil, making them ideal for supporting healthy grass growth.
In summary, while platy structure is typically found under grass sod in compacted or poorly drained soils, blocky, prismatic, or granular structures are more favorable for optimal plant growth and healthy turf.
