An engine operates an ideal, air standard otto cycle with a compression ratio of 8. heat transfer to the engine is from a high temperature reservoir at 1000oc, and heat transfer from the engine to the surroundings at 20oc and 100kpa. at the beginning of the isentropic compression process the pressure and the temperature of the working fluid are 110kpa and 50oc. at the end of the combustion process the temperature is 900oc. calculate: (a) pressure and temperature of the remaining 3 states of the otto cycle. (b) thermal efficiency of the cycle. (c) mean effective pressure. (d) the maximum thermal efficiency for a heat engine operating between the heat reservoirs indicates.

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?
