QUESTION:

Refrigerant 134a enters a water-jacketed compressor operating at steady state at \(-10^{\circ} \mathrm{C}, 1.4 \mathrm{bar}\), with a mass flow rate of \(4.2 \mathrm{~kg} / \mathrm{s}\), and exits at \(50^{\circ} \mathrm{C}\), 12 bar. The compressor power required is \(150 \mathrm{~kW}\). Neglecting kinetic and potential energy effects, determine the rate of heat transfer to the cooling water circulating through the water jacket.
