Homework Statement
An ice making plant consists of a reversed Carnot engine extracting heat from a well- insulated box. The temperature in the icebox is -5C and the temperature of ambient air is 30C. Water of an initial temp 30C is placed in the icebox and allowed to freeze and cool to -5C. If the plant makes 10,000kg of ice, what is the mechanical power required?
Homework Equations
Qwater= c(water)*m*(T2-T1)
Qfreeze= Latent heat of fusion * m
Qice= c(ice)*m*(T2-T1)
n= 1- Q2/Q1
The Attempt at a Solution
I calculated Qwater, Qfreeze, and Qice. I am not sure where to go from here
