A centrifugal fan supplies 4.7m3/s of air at a total static pressure of 325Pa. If the fan efficiency is %06 and rotates at a speed of 950rpm and supplies air with a velocity of 12m/s, determine the fan total pressure, air power, and fan power?

Calculate the thrust of a turbojet engine with an inlet diameter of 4 ft. If an airplane is flying at altitude of 15km at Mach 0.8 with an exit velocity of 900ft/s.  The turbojet engine thrust at 15-km. (in Lbf)

The centrifugal pump is operating under steady flow condition delivers 2270 kg/min of water from an initial pressure of 82740 Pa to a final pressure of 275800 Pa. The diameter of the inlet pipe to the pump is 15.24 cm and the diameter of the discharge pipe is 10.16 cm. Calculate the work of the system in kJ/ min.

Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/min to an adiabaticturbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine thesteam flows to a heater, where it is reheated isobarically to its initial temperature. Neglectkinetic energy changes.(a) Write an energy balance on the turbine and use it to determine the outlet streamtemperature.(b) Write an energy balance on the heater and use it to determine the required input (kW) tothe steam.(c) Verify that an overall energy balance on the two-unit process is satisfied.(d) Suppose the turbine inlet and outlet pipes both have diameters of 0.5 meter. Show that itis reasonable to neglect the change in kinetic energy for this unit.
