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.

An air-standard Carnot cycle is executed in a closed system between the temperature limits of 350 and 1200 K. The pressures before and after the isothermal compression are 150 and 300 kPa, respectively. If the net work output per cycle is 0.5 kJ, determine (a) the maximum pressure in the cycle, (b) the heat transfer to air, and (c) the mass of air. Assume variable specific heats for air.

A Carnot heat engine operates between temperature levels of 600 K and 300 K with 8 MW heat transferred in the boiler. It drives a compressor, which compresses steam from 200 kPa, 200°C to 1 MPa, 500°C. If mass flow rate of the steam is 5 kg/s. determine the following: (a) The power output of the heat engine (kW). (b) The power input of the compressor (kW). (c) The efficiency of the compressor.

If the temperature inside a room is 25°C and the temperature outside is ?10°C: a. What is the maximum relative humidity that can be accommodated inside the room before the window fogs over? (Assume the inside of the window is not insulated from the outside temperature). b. If it is a double-pane window such that the inside of the window is perfectly insulated from the outside, what will the maximum relative humidity be?
