24000 kJ/h = 24000*1000 / 60*60 = 6666.67 W
5 hp = 5*746 = 3730 W
Coefficent of Perfoemance = Heat rejected / work done
= 6666.67 / (3730)
= 1.787
so option c) 1.8 is the correct answer
Add Answer to:
A refrigerator requires 5 hp to provide 24000 kJ/h of cooling. The COP of the refrigerator...

A reheat power plant operates between the pressures of 10 MPa and 5 kPa. Steam enters the high and low pressure turbines at 400 °C. If the steam leaves the high pressure turbine at 4 MPa and steam is at saturated vapour state at the end of both turbines, total specific power output of this power plant is; A heat pump is absorbing heat from the cold outdoors at 5°C and supplying heat to a house at 25°C at a...
