Steam enters the first-stage turbine shown in the figure at 40 bar and 400oC with a mass flow rate of 60,000 kg/hr. Steam exits the first-stage turbine at 20 bar and 400oC. The steam is then reheated at constant pressure to 500oC before entering the second-stage turbine. Steam leaves the second stage as saturated vapor at 0.6 bar. Assume steady state operation and ignore stray heat transfer and kinetic and potential energy effects. Determine the volumetric flow rate of the steam at the inlet to the first-stage turbine, in m3/min, the rate of heat transfer to the steam flowing through the reheater, in kW, and the total power produced by the two stages of the turbine, in kW.

In a pipe of diameter 350 mm and length 75m water is flowing at a velocity of 2.8 m/s. Find the head lost due to friction by using Darcy Weisbach equation?
Answer:
1.71 m
Explanation:
The attachment shows the equation and values used in it. The Moody Friction Factor is not specified in this problem statement, so we have used the value provided by the calculator web site (0.02). The head loss is proportional to that factor, so it is not difficult to find the loss if your factor is different.
Determine the gage pressure at the center of pipe A in pounds per square inch and
in kilopascals.
Answer: the stress is 384 pounds per square inch.
Step-by-step explanation:
Let S represent the stress in the material of the pipe.
Let P represent internal pressure of the pipe.
Let D represent internal diameter of the pipe.
Let T represent the thickness of the pipe.
The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. Introducing a constant of proportionality, k, the expression becomes
S = kPD/T
The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness is 0.75 inch, and the internal pressure is 25 pounds per square inch. It means that
100 = (k × 25 × 5)/0.75
125k = 100 × 0.75 = 75
k = 75/125 = 0.6
The equation representing the relationship becomes
S = 0.6PD/T
If the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inch, then the stress would be
S = (0.6 × 40 × 8)/0.5
S = 384

Amends the FMVSS on air brake systems to improve the stopping distance performance of truck tractors. The rule requires the vast majority of new heavy truck tractors to achieve a 30 percent reduction in stopping distance compared to currently required levels. For these heavy truck tractors (approximately 99 percent of the fleet), the amended standard requires those vehicles to stop in not more than 250 feet when loaded to their gross vehicle weight rating (GVWR) and tested at a speed of 60 miles per hour (mph). For a small number of very heavy severe service tractors, the stopping distance requirement will be 310 feet under these same conditions. In addition, this final rule requires that all heavy truck tractors must stop within 235 feet when loaded to their “lightly loaded vehicle weight” (LLVW).

2. A silo (base not included) is to be constructed in the form of a cylinder surmounted by a hemisphere. The cost of construction per square unit
of surface area is twice as great for the for the hemisphere as it is for the cylindrical side wall. Determine the dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum. Neglect the thickness of the silo and waste in construction.
An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.
The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;
Height of cylinder = 2 × Radius of cylinderReason:
The given parameters are;
Form of silo = Cylinder surmounted by a hemisphere
Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall
Required:
The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum
Solution:
The fixed volume of the silo, V, can be expressed as follows;
[tex]V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3[/tex]
[tex]h = \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 }[/tex]Where;
h = The height of the cylinder
r = The radius of the cylinder
The surface area is, Surface Area = 2·π·r·h + 2·π·r²
The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²
Therefore;
[tex]C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}[/tex]
[tex]C = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}[/tex]At the minimum value, we have;
[tex]\dfrac{dC}{dr} =0 = \dfrac{d}{dr} \left(\dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r} \right) = \dfrac{16 \cdot r^3 \cdot \pi - 6 \cdot V}{3 \cdot r^2}[/tex]Which gives;
16·π·r³ = 6·V
[tex]V = \dfrac{16 \cdot \pi \cdot r^3}{6} = \dfrac{8 \cdot \pi \cdot r^3}{3}[/tex]Which gives;
[tex]h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r[/tex]
h = 2·r
The height of the silo, h = 2 × The radius, 2
Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

5. What is the biggest danger when using
electric drills?
O A. Using the wrong size bit for the hole
required can ruin the drill.
O B. The bit could get caught and throw the
user.
O C. The bit coming loose in the drill can
cause a loss of torque.
O D. Static electricity can build up and
deliver an electric shock to the user.
Answer:
Static electricity can build up and
deliver an electric shock to the user drilling with an electric drill or any drill can create static electricity but with electric drills the static electricity can react with the drills power supply creating a short circuit proceeding to shock you which is why electric drills have rubber grips around them to INSULATE the shock if It does happen (also that's why the drills mostly are made up of non conductive materials.)

If the probability of a bit error is p, what is the probability of a single, double, and triple error in a 10-bit word? Express it in terms of p.
Answer:
single bit error: 10pdouble bit error: 45p²triple bit error: 120p³Explanation:
The probability of n bits being in error is 10Cn × p^n, where ...
10Cn = 10!/(n!(10-n!))
10C1 = 10
10C2 = 45
10C3 = 120
This is the product of the probability that n bits can be in error and the number of ways that n bits can be chosen from the 10 in the word.
n = 1: 10p
n = 2: 45p²
n = 3: 120p³
