Here's my problem:(adsbygoogle = window.adsbygoogle || []).push({});

For each kW of power input to an icemaker at steady state, determine the maximum rate that ice can be produced in kg/h, from liquid water at 0 C. Assume that 333 kJ/kg of energy must be removed by heat transfer to freeze water at 0 C, and that the surroundings are at 20 C.

I know that W = 1 kw, Tc = 0C=273 K, Th = 20C=293 K.

Since the device operates at steady state, W = Qh - Qc.

I also know that W/Qh is less than or equal to (1- Tc/Th)

Could someone give me a hint on where to start with this one? What is the 333 kJ/kg?

Thanks!
