A heat pump (see Problem 5.49) should upgrade 5 MW of heat at 85C to heat delivered
Question:
A heat pump (see Problem 5.49) should upgrade 5 MW of heat at 85◦C to heat delivered at 150◦C. For a reversible heat pump, what are the fluxes of entropy into and out of the heat pump?
Data from problem 5.49
A piston/cylinder has 2 kg water at 1000 kPa, 200◦C that is now cooled with a constant loading on the piston. This isobaric process ends when the water reaches a state of saturated liquid. Find the work and heat transfer and sketch the process in both a P–v and a T–s diagram.
