Acounter-flow, double-tube (shell-and-tube) heat exchanger is used to cool the lubricating oil for large industrial gas turbine engine by cooling water which enters the heat exchanger at 30°c the copper inner tubes have a diameter of 2 cm and negligible thickness, while the inner diameter of the outer annulus (the shell) is 4 cm. water flows through the tube at a rate of 0.18 kg/s, and the oil through the shell at a rate of 0.12 kg/s. the inlet and outlet temperatures of oil are 95°c and 65°c, respectively. assume the tube wall resistance, fouling factors and heat loss to the surroundings are negligible. design the heat exchanger.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
