An ice cube (mass 30 g) at 0°C is left sitting on the kitchen table, where it gradually melts. The temperature in the kitchen is 25°C. Calculate the net change in the entropy of the universe during this process. Is the net change positive, negative, or zero? Is this what you would expect?
Q5 (a) Air enters an adiabatic compressor at 100 kPa and 17°C at a rate of 2.4 m/s, and it exits at 270°C. The compressor has an isentropic efficiency of 84%. Determine: (i) The exit pressure of the air; and (ii) The power required to drive the compressor.
In a container with a fixed volume of 0.5 m3, initially there is refrigerant -134a at a pressure of 200 kPa and a dryness fraction of 40%. Later, heat is transferred from a source at 35°C to the refrigerant until its pressure rises to 400 kPa. Calculate the entropy changes of the system, the surroundings, and the universe during the phase change.
During a reversible process, 2.07 kg/s of gas rejects 336.8 kJ/s of heat isothermally at 24.9°C. For this gas, c, = 2.14 kJ/kg K and c, = 1.62 kJ/kg K. The initial pressure is 552.3 kPa. Determine the work steady flow of the process in hp if APE = 2.8 kJ/s and AKE = 6.5 kJ/s.
Consider a system consisting of a hot body at 70°C and a cold body at 20°C. If 100 kJ of heat is transferred from the hot to the cold body, calculate a) The entropy loss from the hot body and the entropy increase in the cold body. b) How much did the entropy of the universe increase during this transfer? (Assume the bodies are sufficiently large that the temperatures do not change significantly during this process.)
