Answer:

Explanation:

The balanced chemical equation for the reaction between copper(II) oxide (CuO) and hydrogen gas (H2) to form water (H2O) and copper (Cu) is:

CuO + H2 → H2O + Cu

From the equation, we can see that 1 mole of CuO reacts with 1 mole of H2 to form 1 mole of H2O.

Therefore, if we start with 2 moles of CuO, we would need 2 moles of H2 to react completely and form 2 moles of H2O.

CuO + 2H2 → 2H2O + Cu

So, 2 moles of CuO would form 2 moles of H2O.

Explanation:

mass=19kg

density=800kg/m³

volume=?

as we know that

density=mass/volume

density×volume=mass

volume=mass/density

putting the values

volume=19kg/800kg/m³

so volume=0.02375≈0.02m³

Answer:

a) \(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b) \(\mathbf{\sigma _c = 4.3067 \ Btu/hr ^0R}\)

Explanation:

From the properties of Super-heated Refrigerant 134a Vapor at \(T_1 = 40^0 F\), \(P_1 = 30 \ lbf/in^2\) ; we obtain the following properties for specific enthalpy and specific entropy.

So; specific enthalpy \(h_1 = 109.12 \ Btu/lb\)

specific entropy \(s_1 = 0.2315 \ Btu/lb.^0R\)

Also; from the properties of saturated Refrigerant 134 a vapor (liquid - vapor). pressure table at \(P_2 = 160 \ lbf/in^2\) ; we obtain the following properties:

\(h_2 = 115.91 \ Btu/lb\\\\ s_2 = 0.2157 \ Btu/lb.^0R\)

Given that the power input to the compressor is 2 hp;

Then converting to  Btu/hr ;we known that since 1 hp = 2544.4342 Btu/hr

2 hp = 2 × 2544.4342 Btu/hr

2 hp = 5088.8684 Btu/hr

The steady state energy for a compressor can be expressed by the formula:

\(0 = Q_c -W_c+m((h_1-h_e) + \dfrac{v_i^2-v_e^2}{2}+g(\bar \omega_i - \bar \omega_e)\)

By neglecting kinetic and potential energy effects; we have:

\(0 = Q_c -W_c+m(h_1-h_2) \\ \\ Q_c = -W_c+m(h_2-h_1)\)

\(Q_c = -5088.8684 \ Btu/hr +200 \ lb/hr( 115.91 -109.12) Btu/lb \\ \\\)

\(\mathbf{Q_c = -3730.8684 \ Btu/hr}\)

b)  To determine the entropy generation; we employ the formula:

\(\dfrac{dS}{dt} =\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

In a steady state condition \(\dfrac{dS}{dt} =0\)

Hence;

\(0=\dfrac{Qc}{T}+ m( s_1 -s_2) + \sigma _c\)

\(\sigma _c = m( s_1 -s_2) - \dfrac{Qc}{T}\)

\(\sigma _c = [200 \ lb/hr (0.2157 -0.2315) \ Btu/lb .^0R - \dfrac{(-3730.8684 \ Btu/hr)}{(40^0 + 459.67^0)^0R}]\)

\(\sigma _c = [(-3.16 ) \ Btu/hr .^0R + (7.4667 ) Btu/hr ^0R}]\)

\(\mathbf{\sigma _c = 4.3067 \ Btu/hr ^0R}\)

At 1.2mpa pressure and 50c

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53
(Cop) = 4.490

Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

An architecture describes the components of a system, what do they do, and how do they interrelate/interact with each other ; yes.

What is the components ?

A component is a self-contained, independent piece of functionality that can be integrated into a larger system. It is usually a software entity, such as a library, class, or module, but can also refer to hardware or physical components, such as an electronic circuit. Components encapsulate a set of related functionalities, often with a user interface, and are designed to be reusable and replaceable. They can be exchanged between different systems, either as a unit or with their individual parts. Components are often developed by third parties, and can be integrated into existing systems to provide new or enhanced features.

Answer: the temperature of the inner surface is 599.55 K

Explanation:

first, let Am²  represent area of the oven surface

now heat transfer rate due to convection

qconv = hAΔT

where ΔT is temperature difference in kelvin (To -Ts) temperature of outer surface - temperature of surroundings

ΔT = 400K - 300k = 100k

and h = 20 W/m².K

so we substitute

qconv = 20 × A × 100 = 2000A W

Now heat transfer due to emission

qemi = ∈α(To⁴ - Ts⁴)A

∈ is emissivity =  0.8, α is boltzman constant = 5.67×10⁻⁸ W/m⁻²K⁻⁴

so we substitute

qemi = 0.8 × 5.67×10⁻⁸ (400⁴ - 300⁴)A

qemi = 4.536×10⁻⁸ × 1.75×10¹⁰ × A

qemi =  793.8A W

NOW total heat loss rate = Qconv + Qemi

2000A + 793.8A = 2793.8A W

so since outer surface is to be maintained at a temp of 400K then heat must be transferred from inner surface to outer surface at the same rate.

Therefore

Heat transfer rate to outer surface by conduction = kA(Ti-To)/L

k is thermal conductivity  0.7 W/m.K, Ti is temperature of inner surface, L is the thickness of plate  0.05m

so Heat transfer rate = 0.7× A × ( Ti - 400 ) / 0.05

Now

This heat transfer rate equals heat loss rate

so  0.7× A × ( Ti - 400 ) / 0.05  =  2793.8 × A

divide both side by A

THEREFORE

Ti = 400 + 199.55

Ti = 599.55 K

∴  the temperature of the inner surface is 599.55 K

Most modern vehicles, according to technician a, have ABS. According to technician B, ABS reduces wheel lockup (skidding) by monitoring wheel speed with sensors in the wheel. They are both right.

ABS stands for anti-lock brake system, to put it simply. It is conceivable for the brakes' grip to be greater than the tire's contact with the road when braking is applied to a wheel. The wheel "locks up" and stops rotating when this occurs.

As soon as the wheel locks, an ABS system releases the brake pressure. During strong braking, this occurs repeatedly and can be felt as a pulsating sensation on the brake pedal. Even in emergency braking scenarios, the car maintains a high degree of stability by evenly distributing brake pressure over each wheel.

Answer:

  Av = -800

Explanation:

The gain to the output of the first op-amp is ...

  A1 = -R2/R1 = -1000/10 = -100

The gain of the voltage divider R3/R4 is ...

  A2 = R4/(R3+R4) = 10/(10+10) = 1/2

The gain of the second op-amp circuit from the positive terminal to the output is ...

  A3 = 1+ R5/R6 = 1 + 150/10 = 16

Then the total circuit gain is ...

  Av = A1×A2×A3 = (-100)(1/2)(16)

  Av = -800

Based on the information provided by these technicians, both of them are correct.

According to heating, ventilation, and air conditioning (HVAC), heat in an air-conditioning system generally flows from the hotter object to the colder object.

As the refrigerant evaporates in a small radiator-type unit (evaporator), it absorbs heat as it changes phase from liquid to gas. Also, as the heat is being absorbed by the refrigerant, the small radiator-type unit (evaporator) becomes cold.

Regression is a machine learning algorithm used for predicting continuous numeric values based on input data.

Given a set of input data and corresponding labels, regression aims to find the linear model that best fits the data by minimizing the norm between the predicted values and the ground-truth labels. This process involves calculating the distance between the predicted output and the actual output for each data point and then minimizing the sum of these distances. By minimizing this norm, regression is able to find the optimal set of coefficients for the linear model that best predicts the output values for the given input data.

Mass is the measure of the amount of matter an object contains. It is measured in kilograms (kg) in the International System of Units (SI). Mass is also known as a measure of inertia, which is the resistance of an object to change its velocity or its direction. In other words, mass is the measure of an object's resistance to acceleration.

The specific thrust is the amount of thrust generated per unit mass flow rate of air through the engine. It can be calculated by the following equation:

T = m * (Vexit – Vinlet)

where m is the mass flow rate of air and Vexit and Vinlet are the exit and inlet velocities respectively.
