Question:
A 10 kW pump is used to pump liquid ammonia from 5 bar and 0 °C to 25 bar. The efficiency of the pump is 62%.
Transcribed Image Text:
a) What is the mass flow rate (kg/s) delivered by the pump? b) What is the temperature at the exit of the pump? c) Calculate the rate of entropy generation (in kW/K). Additional data for liquid ammonia: density = 0.64 g/cm³; Cp = 1.1 kJ/kg K; ß = 2.095 × 10- K-¹.
