As discussed in class, rotor wheel turbines are commonly used in hydroelectric power plants to generate electric power. In the Pelton wheel design below with radius r = 2 m, a high speed water jet (with Vj = 50 m/s and flow rate 10 m3 /s) impinges on buckets making an angle β=160 degrees, forcing the wheel to rotate at constant angular speed ω = 150 revolutions per minute. Calculate the power delivered to the rotor if there are 10 jets as described above surrounding the Pelon wheel.

The rest of the questions are thus: 4) Calculate the air temperature and pressure in the pump at the end of the following expansion stroke, just before the piston uncovers the orifice (orifice dimensions are neglectable).5) Calculate the mass and temperature of air in the pump (i.e. the cylinder andconnecting pipe) after the orifice has been exposed and the pressure has risen to atmospheric pressure (bottle valve is now closed).7) Calculate the piston position and the air temperature in the pump during the next compression stroke at the time when the valve to the gas bottle opens again.8) Calculate the pressure in the bottle when no more air can be transferred by the pump. (This will be after an undetermined number of pumping cycles).
FLOW THROUGH PIPELINE PROBLEM Process water is pumped from the main storage tank (A) to process tanks (B) and (C). The pipeline from main storage tank (A) to the centrifugal pump inlet is 3-inch Schedule 40 commercial steel pipe, with an equivalent length of 61 meters. The line from the centrifugal pump discharge to the tee (entry into leg) where the pipeline branches is also 3-inch Schedule 40 pipe, with an equivalent length of 30.5 meters. The pipeline from the tee to process tank (B) is 1.5-inch Schedule 40 pipe, with an equivalent length of 183 meters. The pipeline from the tee to process tank (C) is 2-inch Schedule 40 commercial steel pipe, with an equivalent length of 183 meters. The equivalent lengths as given do not include four (4) gate valves, one (1) between storage tank (A) and the centrifugal pump, one (1) between the centrifugal pump and the tee, and one (1) each at process tanks (B) and (C); and two (2) globe valves (bevel seat), globe valve “X” in line from the tee to…
