At a steady state, a thermodynamic cycle operating between hot and cold reservoirs at 1000K ands respectively. The cycle receives energy by heat transfer from the hot reservoir at a rate of 1500kW, and discharges energy by heat transfer to the cold reservoir. The cycle develops power at a rate of (a)0 (b) 250 kW and ()1000kW For each case, based on the Clausius inequality, determine whether the cycle operates reversibly, irreversibly or is impossible.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
