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).

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
