Explanation:

Heat loss from a 1.3-m2 black surface at 1350C to the surrounding air at 27 0C by convection with a convection heat transfer coefficient of 20W/m2.

0C, and by radiation to the surrounding surfaces at 20 0C can be determined as follows:Total rate of heat loss from the surface in watts is given by the sum of the rate of heat loss due to convection and radiation from the surfaceMathematically,H = Hconv + Hrad...[1]The rate of heat loss due to convection is given by the relation,Hconv = h× A × (Ts - Ta)...[2]where, h is the convection heat transfer coefficient, A is the area of the surface, Ts is the surface temperature and Ta is the surrounding fluid (air) temperature.

Substituting the given values in eq[2], we haveHconv = 20× 1.3× (135 - 27) = 3434 WNow, rate of heat loss due to radiation is given by the relation,Hrad = ε × σ × A × (Ts4 - Tsur4)...[3]where, ε is the emissivity of the surface, σ is the Stefan-Boltzmann constant, Ts is the surface temperature and Tsur is the average surrounding surface temperature.Substituting the given values in eq[3], we haveHrad = 1× 5.67×10-8× 1.3× (135 + 273)4 × (135 + 273 + 20)4 = 345.15 WThus, substituting the values of Hconv and Hrad in eq[1], we get the total rate of heat loss from the surface in watts asH = Hconv + Hrad= 3434 + 345.15 = 3780.15 WTherefore, the total rate of heat loss from the surface is 3780.15 W.

Answer:

\(Length = 9558.7\ mils\)

Explanation:

Given

\(diameter = 82.2\ mils\)

\(Strands = 37\)

Required

The length of the wire

First, we calculate the circumference (C) of 1 strand of the wire

\(C = \pi d\)

\(C = \frac{22}{7} * 82.2\)

\(C = \frac{22* 82.2}{7}\)

\(C = \frac{1808.4}{7}\)

The length of the 37 strands is:

\(Length = 37 * C\)

\(Length = 37 * \frac{1808.4}{7}\)

\(Length = \frac{37 * 1808.4}{7}\)

\(Length = \frac{66910.8}{7}\)

\(Length = 9558.68571429\)

\(Length = 9558.7\ mils\) --- approximated

Answer:

24.52% efficiency

Explanation:

Knowns:

Mass = 50 kg

Height = 6 m

Time = 3 s

Indicated Power = 4 kW = 4000 W

Acceleration Due to Gravity = 9.81 m/s^2

Actual Power = Potential Energy / Time = mgh / t

Actual Power = (50 kg * 9.81 m/s^2 * 6 m) / 3 s = 981 W

Motor Efficiency = (Actual Power / Indicated Power) * 100 = (981 W / 4000 W) * 100 = 24.52%

Rate of discharge in cumecs: 0.0048m³/s.

Velocity flow: 24m/s.

a. Convert from litres to m³.
120L*1000= 120000mL

120000mL=120000cm³

120000cm³/100³=0.12 m³.

b. Rate of discharge.

If  0.12 m³ where discharged in 25 seconds, the rate of discharge is:

0.12m³/25s = 0.0048m³/s.

Let's refer to the fluid mechanics equation that relates volume flow, area and velocity. This is the formula:

\(\frac{dV}{dt}=Av\); where the expression \(\frac{dV}{dt}\) is the volume flow rate (in m³/s); A is the cross-sectional area of the pipe (in m²), and v is the velocity flow (in m/s).

a. Solve the equation for v.

\(\frac{dV}{dt}=Av\\ \\(\frac{dV}{dt})/A=v\\ \\v=(\frac{dV}{dt})/A\)

b. Calculate the cross-sectional area of the pipe.

The cross-sectional area of the pipe is a circle. Hence, the formula of this area is:

\(A=\pi r^{2}\)

We'll have to convert the diameter to meters, because the formula for flow velocity needs the area in m². Let's go ahead and do that.

\(50mm/1000=0.05m\).

We were given the diameter, and the formula uses the radius, but the radius is just half of the diameter, therefore, we can substitute in toe formula like this:

\(A=\pi (\frac{0.05}{2} )^{2}=0.0020m^{2}\)

c. Substitute in the new expression for velocity flow and calculate.

\(v=(\frac{dV}{dt})/A\\ \\v=(\frac{0.048m^{3} }{1s})/(0.0020m^{2} )\\\\ v= 24m/s\)

To estimate the settlement in 25 years using the method of Schmertmann et al., we can use the equation (9.30) provided. However, since you mentioned the term "creep," we need to consider the creep settlement as well.

The equation (9.30) for estimating the settlement is:
Δs = (2.5 * Δσvc) * (log10(t + 0.05) - log10(t0 + 0.05))
Where:
Δs is the settlement in meters
Δσvc is the increase in vertical effective stress in kN/m²
t is the time in years
t0 is the reference time (initial time) in years
First, let's calculate the increase in vertical effective stress (Δσvc) using the equation:
Δσvc = qc * Bq * Nγ
Where:
qc is the average cone resistance in MN/m² (converted from kN/m² by dividing by 1000)
Bq is the width of the foundation in meters
Nγ is the correction factor for the foundation width
Given that qc = 10 MN/m², Bq = 2 m, and Nγ = 0.5 (for a square foundation), we can substitute these values into the equation:
Δσvc = (10 MN/m²) * (2 m) * (0.5) = 10 MN/m²
Now, let's calculate the settlement (Δs) at 25 years using the equation (9.30):
Δs = (2.5 * 10 MN/m²) * (log10(25 + 0.05) - log10(t0 + 0.05))
Since the reference time (t0) is not mentioned, we'll assume it to be the current time, which is 0 years. Substituting the values into the equation:
Δs = (2.5 * 10 MN/m²) * (log10(25 + 0.05) - log10(0 + 0.05))
Simplifying the equation, we get:
Δs = 2.5 * 10 MN/m² * (log10(25.05) - log10(0.05))
Now, to calculate the creep settlement, we need more information such as the rate of creep. Without that information, we cannot determine the amount of settlement due to creep.

While tweeting the genome sequence may be a creative and attention-grabbing way to share scientific information, it may not be the most practical or efficient method for reporting such complex data.

To report the full 28,000 base long genome sequence to scientists, it would take 200 tweets, given the length limit of 280 characters per tweet. If each tweet takes 30 seconds to type and post, then it would take a total of 100 minutes (200 tweets x 30 seconds per tweet) or 1 hour and 40 minutes to report the entire genome sequence to the scientists. This assumes that there are no interruptions or technical issues during the process of typing and posting the tweets. It also assumes that the scientists are monitoring the tweets in real-time and are able to compile and analyze the information as it is being tweeted. In reality, scientists may prefer to receive the genome sequence in a more streamlined and efficient manner, such as through a file transfer or database upload.

Answer:

a. 1.6 Kbytes/min

b. 10.417 Mbytes/min

Explanation:

a. The DSL modem operates at 768 Kbits/sec.

But,

    8 bits = 1 byte and 1 Kbit = 1 000 bits, so that:

       = \(\frac{768 000}{8}\)

      = 96 000 bytes

Therefore, the modem operates at 96 Kbytes/sec.

The byte to be received in 1 minute can be calculated thus;

Since 60 seconds = 1 minute, then:

 = \(\frac{96000}{60}\)

  = 1600

 = 1.6 Kbytes/min

The modem receives 1.6 Kbytes/min

b. The USB sends 5 Gbits/sec.

But, 8 bits = 1 byte and 1 Gbit = 1000000000 bits so that:

= \(\frac{5000000000}{8}\)

= 625000000

= 0.625 Gbytes

The USB sends 0.625 Gbyte/sec.

Since 60 seconds = 1 minute, then:

=  \(\frac{625000000}{60}\)

= 10416666.67

= 10.417 Mbytes/min

An anti-lock brake system uses all of the following to prevent the loss of tire adhesion during hard braking: Electronic Control Unit, Wheel Speed Sensors, Hydraulic Control Unit, and Valves.

In order to avoid skidding and maintain control of a vehicle during hard braking, an anti-lock braking system (ABS) employs an electronic control unit (ECU), wheel speed sensors, hydraulic control unit, and valves. The ECU obtains data from wheel speed sensors and, based on that information, controls the hydraulic pressure to the brakes by sending signals to the hydraulic control unit. The hydraulic control unit, on the other hand, modulates the hydraulic pressure sent to the brakes so that the wheels do not lock up during braking.

ABS works by allowing a small amount of braking force to be released and reapplied to the wheels multiple times per second. This process helps to keep the wheels from locking up while still providing braking force to slow the vehicle down. Because the ABS system applies and releases the brakes rapidly, it enables the wheels to maintain traction with the road surface, allowing the driver to steer the vehicle to avoid obstacles or accidents.

The smoothing system using convolution with a box of length N and height 1/N can be described by the following equation:

h1n=(un-un-N)/N

Step-by-step explanation:

To find the coefficients {a, b} of the linear constant coefficient difference equation (LCCDE) for this system, we can rewrite the equation as follows:

h1n = un/N - un-N/N

If we let a = 1/N and b = -1/N, we can express this equation as an LCCDE:

a * un + b * un-N = h1n

For N=10, the coefficients {a, b} are:

a = 1/10 = 0.1

b = -1/10 = -0.1

The coefficients for the system h1n=0.8nun can be found in a similar manner. If we let a = 0.8 and b = 0, we can express this equation as an LCCDE:

a * un + b * un-N = h1n

The coefficients for this system are:

a = 0.8

b = 0

Note that the LCCDE for the smoothing system using convolution with a box of length N and height 1/N is a first-order difference equation, as it depends on the current and previous values of the input signal (un and un-N). The LCCDE for the system h1n=0.8nun is also a first-order difference equation, as it depends only on the current value of the input signal (un).
