Air enters the compressor of a gas turbine plant at ambient conditions of 100 kPa and 25 °Cwith a low velocity and exits at 1 MPa and 347 C with a velocity of 90 m/s. The compressionprocess is adiabatic, and the power input is 200. Determine the mass flowrateof the air through the compressor.
A vessel initially contains 5.0 kg of liquid water and 2.0 kg of ice at 0°C. Energy is added until the ice has just melted. The temperature at the boundary where heat transfer occurs is taken to be the system temperature during the process. The enthalpy of melting is 333.5 kJ/kg. Consider the following processes used to melt the ice. a. Heat is added from the environment at 20°C. Determine the entropy flux and the total entropy generation, both in kJ/K. b.
