Air enters a heat exchanger at a volumetric flow rate of 50 m/min at 305 k and 100 kpa. air exits at 295 k and 95 kpa (this means that the air stream of the heat exchanger is not ideal, as there is a drop in pressure). r-134a enters the heat exchanger at 0.5 mpa at a quality of 0.2. r-134a exits at 20°c. + a. draw the t-v diagram for air.' b. draw the p-v diagram for air.' c. draw the t-v diagram for r-134a. d. draw the p-v diagram for r-134a.' e. determine the mass flow rate of r-134a.' f. determine the heat transfer from the air stream in units of kj/min. g. clearly outline every assumption that must be made to determine the mass flow rate and heat transfer.
