Air is flowing through a venture-meter whose diameter is 2.6 in at the entrance part (location 1) and 1.8 in at the throat (location 2). The gage pressure is measured to be 12.2 psia at the entrance and 11.8 psia at the throat. Neglecting frictional effects, show that the volume flow rate can be expressed as 2(P-P2) P(1 - AJA}) and determine the flow rate of air. Take the air density to be 0.075 Ibm/ft3.

A fan is used to extract 140m3 air per minute from a large room. A circular duct of diameter 0.53 m connects the fan to the room, and the air is exhausted from the fan into the atmosphere through a conical diffuser that increases in diameter from 0.53 m to 0.8 m. A manometer shows that the pressure in the room is sub-atmospheric and the water height differential across the manometer is 6 mm. Neglecting losses, calculate:a. The static and stagnation pressures upstream of the fanb. The static and stagnation pressures downstream of the fanc. The power supplied by the fan to the air[Hint: define the following stations: 1. The room, 2. Immediately upstream of fan, 3. Immediately downstream of fan, 4. The atmosphere]

A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3. Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.
