An ice making machine takes in water at a temperature of 16*C and produces ice cubes at -6*C.Water is taken in at the rate of 1 kg every 6 minutes and the input power to the machine itself is 3kW. Assuming the specific heat capacity of water is 4200 J/kgK, the specific heat capacity of ige is 2100 J/kgC and the specific latent heat of fusion of the ice is 335 kJ/kg, determine the efficiency of the ice making machine.

To determine the efficiency of the ice-making machine, we can use the formula for efficiency in terms of energy:

Efficiency =Output Energy / Input Energy Efficiency

The input energy is the energy required to cool the water from its initial temperature to the freezing point, then freeze it into ice. The output energy is the latent heat of fusion released during the freezing process.

Let's calculate the input and output energies step by step:
