1. A steady stream of R-410a at ambient temperature, 20?C, and 800 kPa enters a solar collector and exits at 80?C, 600 kPa. Calculate the change in exergy of the R-410a.

2. A heat pump has a COP of 2 using a power input of 3 kW. Its low temperature is T0 and its high temperature is 80?C, with an ambient at T0. Find the fluxes of exergy associated with the energy fluxes in and out.
