A piston-cylinder device initially contains 1.78 kg saturated liquid water at 200°C. Now heat is transferred to the water until the volume quadruples and the cylinder contains saturated vapor only. Determine (a) the final volume of the tank, m (Round to six decimal places.) (b) the final temperature and pressure, MPa and (c) the internal energy change of the water kJ 0 Water 1.78 kg 200 C
QUESTIONS 1. Refrigerant-134a is cooled by water in a condenser. The refrigerant enters the condenser at a pressure of 1 MPa and a temperature of 70°C at a flow rate of 6 kg / min and exits at a temperature of 35 °C. Cooling water enters the condenser at 300 kPa pressure and 15 °C temperature and exits at 25 °C temperature. By neglecting pressure losses, Calculate; a) mass flow of cooling water b) the heat transfer from the refrigerant...
A frictionless piston-cylinder device contains a saturated liquid-vapor mixture of water at 373K. During a constant pressure process, 600 kJ of heat is transferred to the surrounding air at 300K. Asa result, part of the water vapor contained in the cylinder condenses. Determine (1) the entropy change of the water, (2) the entropy change of the air (3) the total entropy generation during this process.
Saturated water vapor which is initially at 500 kPa is contained in a piston-cylinder device arranged to maintain a constant temperature. The piston is now moved until the water becomes a saturated liquid. How much work and how much heat (in kJ/kg) are transferred during this process?
