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.

Answers

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.

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?
​

Answers

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.

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?​

Answers

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.
