Multi-processors computer operates in a server room in a building of weather station located in the mountains at altitude of 3400 m computer is cooled by two 2 w fans located at the outlet from chassis. the thermal power of each processor is 65 watt. the temna 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 so 70.6 m/min, respectively, while diameters of fans are 0.1 m. determined the number of processors in the computer. neglect heat in surroundings from the computer and the change in kinetic energy of cooling air as well as assume no variation in the statie nr may be treated as an ideal di-atomic gas with gas constant 287 j/(kgk).
