1. A Venturi meter with an inlet diameter of 0.6 m is designed to handle 6 m3 /s of standard air. What is the required throat diameter if this flow is to give a reading of 0.10 m of alcohol in a differential manometer connected to the inlet and the throat? The specific gravity of alcohol may be taken as 0.8.
2. The pressurized tank shown has a circular cross section of 6 ft in diameter. Oil is drained through a nozzle 2 in. in diameter in the side of the tank. Assuming that the air pressure is maintained constant, how long does it take to lower the oil surface in the tank by 2 ft? The specific gravity of the oil in the tank is 0.85 and that of mercury is 13.6.

A rigid tank contains 10 kg of air at 345 kPa and 27 Celsius. The air is now heated until its pressure doubles. What is the volume of the tank? What is the amount of heat transfer?
At the instant shown, determine the velocity of the piston, the velocity of the point C and the angular velocity of the connecting rod.
Reheat is added to an ideal Rankine steam power cycle to improve it’s efficiency and turbine exit quality. Steam enters the HP turbine at 15 MPa and 600C. Steam exits the HP turbine at 4 MPa and enters the boiler for reheat. Then the steam enters t..
