) Rate of heat rejection from the turbine

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).

The 36% -in pump of the figure below is to pump 20,000 gpm of water at 1,170 rpm from a reservoir whose surface is at atmospheric pressure (i.e. 14.7 psia). a) If head loss from the reservoir to the pump inlet is 6 ft, where should the pump inlet be placed to avoid cavitation for water. The vapor pressure of water at 60°F is 0.26 psi. b) Determine the required brake horsepower. pressure differential across it, is to be fixed at 1 m of mercury (density = 13,600 kg/m³). 50 c) The water is to be transported in an 80 cm pipe, and the engineer would like to measure the flow rate downstream of the pump using an orifice meter.

A reciprocating compressor is operating at 800RPM. Suction pressure and discharge pressure are held constant by other means that have nothing to do with the compressore . The speed is increased from 800 - 840 Rpm (a 5% increase) a) What is the change in the flow rate through the compressor? b) What is the change in the pressure rise through the compressore? c) What is the change in the power that must be delivered to the compressor?
