Multi-processors computer operates in a server room in a building of weather station located in the mountains at altitude of 3000 m. the computer is cooled by three 1.5 w fans located at outlets from chassis. the number of processors is 4. the temperature and pressure in the server room are 25°c and 66.63 kpa, respectively. the temperature and air velocity at the outlets from the chassis are 50°c and 40.0 m/min, respectively, while diameters of fans are 0.1 m. determine the thermal power of each processor. assume that 100 w is lost to the surroundings through chassis walls. neglect the change in kinetic energy of cooling air as well as assume no variation in the static pressure. the air may be treated as an ideal di-atomic gas with gas constant 287 j/(kgk).

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?
