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
a hallow steel tube 3.5m long has external diameter of 120mm. in order to determine the internal diameter the tube was subjected to a tensile load of 400KN and extension was measured to be 2 mm. if the modulus of elasticity for the tube material is 200 GPa. determine the internal diameter of the tube.

How to make coconut harder
Now hear me out: Steel-Coated Coconuts
If you want to make a coconut harder you can take that shell up to heights its natural husk never even knew it could reach! Combining the raw, brown scraglley-ness with the tough, durable properties of steel would most definitely make a coconut harder.
Valid answer? Probably not.

A gas turbine power plant is being designed using an air-standard Brayton cycle. Air enters the compressor with a volumetric flow rate of 7 m3 /s at 100 kPa, 300 K. The turbine inlet temperature is expected to be 1400 K. The compressor pressure ratio is 10. The turbine exhaust goes back to the atmosphere at 100 kPa. (a) Draw the schematic and T-s diagrams. (b) Determine the thermal efficiency. (c) Determine the back work ratio of this power plant.

1. A drawing of a cabinet shows that its dimensions are 9cm. by 4cm. The drawing indicates 1:50 scaling. What are the actual dimensions of the cabinet?
2. Bongbong is tasked to draw a floor plan with a scale of 1:100. If the total length of the actual house is 8 meters, what will be its corresponding measurement in centimeters in floor plan?
3.The length of a bedroom measures 2.5 m., what will be the measurement in centimeters to be used in the drawing if it is in 1:50 scale?
Explanation:
This means that for every 1 cm on the drawing, there is 80 cm in reality. To put it another way, take this
1:80 means that the building is 80 times the size of the drawing
80:1 means that the drawing is 80 times the size of the building
If it were 80:1, the drawing itself would be over 100m long.
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.
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.)

Answer:
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).

The reference OSHA standard requires several important characteristics of a PFAS. The employer must ensure that personal fall arrest systems (PFAs) must:
a. Limit the maximum arresting force on the employee to 1,800 pounds (8 kN). The figure used above must be based on the use of a full body harness.
Maximum arresting force is the highest amount of force that the fall protection system and the individual attached to the system will face as gotten by the deceleration device.OSHA regulations gives the system performance criteria for a personal fall arrest system.
From the above, we can therefore say that The reference OSHA standard requires several important characteristics of personal fall arrest systems (PFAs) as employers must reduce the maximum arresting force on the employee to 1,800 pounds (8 kN) using full body harness.

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.
