Consider a steam turbine where steam enters with a pressure of 10 MPa and temperature 500 °C, and expands adiabatically to 5 kPa. The isentropic turbine efficiency is 80%. Determine the turbine exit quality.
Calculate the isentropic efficiency of the turbine if the exhaust temperature of air is 60 °C. Assume that the average specific heat Cp for air during the process is 1.013 kJ/kg°C.
If the pH level of the reservoir is ok, the results at each location will have varying results, with an average pH of 8.5 and a standard deviation of 0.22. If the pH level of the reservoir is ok, what is the probability that the sample average is
Heat transfer between the compressor and its surroundings can be ignored. Kinetic and potential energy effects are also negligible. Determine (a) the exit temperature, in °C. (b) the work input, in kJ per kg of refrigerant flowing.
Calculate the volume flow rate of water if the pressure at A is 120 psi and the pressure at B is 105 psi. Use Darcy-Weisbach for this analysis.
