Air is made to flow through a well-insulated pipe by a blower as shown in the figure. It is desired that 50ft3/s of air flow by A. The inlet pressure pAA is 10psia and the temperature is 60F (density =0.052lbm/ft3 ). Also, inlet velocity is 91.7ft/s. The exit temperature of air is 90F (density =0.072 lbm/ft3 ), and exit velocity is 183.3ft/s. Assume the specific heat at constant volume Cv as. 0.171Btu/bbmR and independent of temperature. Mass flow rate of air is 2.6lbm/s and. Change in specific enthalpy is 5590 ft1bf/bbm. The power required for the blower if it is 93.7% efficient is hp Hint: Use first law in the open system and without heat loss and potential energy. Convert units to hp using 550ft.lbff/s.hp. 15540 28.2 20.3 30.2
