Amixing chamber operating at steady state at 100 kpa receives a saturated liquid-vapor mixture of water at a first inlet at 0.8 kg/s and a quality of 0.9, steam enters at a second inlet at 2 kg/s and 200°c, and liquid water enters at a third inlet at 1.2 kg/s and 95°c. all h2o leaves through a single exit at 100 kpa. unfortunately, the insulation fell off part of the mixing chamber, so heat is lost from the chamber at a rate of 60 kw. a. determine the mass flow rate of the stream leaving. b. determine the temperature of the stream leaving. c. draw the four state points on a t-v diagram. d. draw the four state points on a p-v diagram. e. determine the temperature of the stream leaving if the insulation is fixed.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
