An ice-making machine operates with the maximum efficiency allowed by thermodynamics (it is a Carnot engine). It takes heat from water at 0 C and discards heat to a room at 23.32 C. Suppose that 34 kg of water at 0 C are converted to ice at 0 C. How much work must be done by the machine to accomplish this? The latent heat of fusion of water is L f = 33.4 x 10 5 J/kg.

We have a Carnot engine operating between a hot reservoir A and a cold reservoir B. The work produced in the engine is used to power a flywheel. The hot reservoir is boiling water at p0 = 1 bar and Ta = 373K. The cold reservoir is a block of ice at p0 and Tb = 273K (latent heat = 3.3E5 J/kg). For the flywheel we know that Inertiamoment = 2kg m^2, mass = 6kg, c = 418J/kg K. Final...
