A cold storage plant is required to store 50 tons of fish. The temperature at which fish was supplied is 35°C while the storage temperature of fish was taken as -10°C.
Cp of fish above freezing point = 2.94kJ/kg°C
Cp of fish below freezing point = 1.26 kJ/kg°C

1. Freezing point of fish = -5°C
   Latent heat of fish = 250 kJ/kg. If the cooling is achieved in 12h, find:
   a) Capacity of the refrigerating plant
   b) Carnot COP
   c) If actual COP = Carnot COP/2.5, find the power required to run the plant
