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.
