8: There is a boundary between a system A with a low temperature TL = 25 C and another system B with a high temperature TH = 89 C. The surrounding of the two systems has an equilibrium temperature 15 C.
a: Schematically sketch the transfer diagrams of temperature, heat, entropy, and exergy across the boundary between A and B.
b: Calculate the entropy at B and the entropy generation if the entropy at A is 2.9 kJ/K.
c: Calculate the exergy at B and the exergy destruction during the process.

In a low temperature drying system, air at 60°C and 10% Relative humidity passes over a bed of diced carrots at 20 kg-dry air/sec. The rate of water removal from the carrots Is measured by difference in total weight over time and found to be approximately .16 kg-water/sec. In the system described above, calculate the temperature and relative humidity of the air exiting the drying system.
