A boiler feedpump receives 10 °C water at a pressure of 500 kPa. The discharge pressure is 2 400 kPa. Given a pump capacity of 160 000 kg/h, and after correcting for the temperature of the water, what is the power supplied to the water? (84.5 kW) 2. Water is supplied to a pump at a pressure of 200 kPa. The power transferred to the water is estimated to be 30 kW. The pump discharge pressure is 2 200 kPa and the specific volume is 0.00106 m3/kg. Estimate the amount of water pumped in cubic meters per min. (0.90 m3/min.) I 3. Air enters a compressor with a velocity of 6.0 m/s and an enthalpy of 233 kJ/kg and leaves with a velocity of 12 m/s and an enthalpy of 477 kJ/kg. Assuming adiabatic compression and negligible change in potential energy, calculate the work required to compress 1.0 kg of air. (244 kJ/kg) 4. An air compressor is supplied with air at 101.3 kPa and a specific volume of 0.804 m3/kg. The air is discharged at 700 kPa and a specific volume of 0.162 m³/kg. The initial and final internal energies are 37.2 kJ/kg and 114 kJ/kg respectively. The cooling water removes 88.0 kJ/kg of air compressed. The change in kinetic and potential energy may be neglected. Calculate (a) the specific work required, (b) the power required given a mass flow rate of 45.6 kg/min. Also (c) if the heat being rejected is transferred to cooling water flowing through a coil, and the cooling water picks up 10ºC across that coil, and the pump forcing that cooling flow has a 100 kPa AP across it, calculate the power required to drive the cooling water pump (197 kJ/kg, 150 kW, 160 W) 5. Wet steam is throttled from 1000 kPa to 10 kPa and 130 °C. Find the dryness fraction at state 1. [98.3%] 6. Steam enters a pressure reducing valve at a pressure of 2000 kPa, dry saturated. It is throttled adiabatically to 100 kPa. What is the temperature and internal energy of th 162 °C 2600 4W/kg)
