A heat pump units operates between two heat reservoirs with temperatures of 270 and 330 K. the heat pump its self has a temperature of 255 K during heat addition from the 270 K reservoir and a temperature of 350 K during heat rejection to the 330 K reservoir. The COP of the actual unit is 3.40 and the heat transfer from the 270 K reservoir is 2000 kJ/min
Determine the irreversibility, in kJ/min, for (1) the heat pump unit, (2) the low heat transfer process, and (3) the high temperature heat transfer process and (4) find the effectiveness. (5) Which process has the largest irreversibility?
