A fan running at 1480 rpm takes in 6 m^3/min of air at inlet conditions of P_1=950 mbar and T_1=15^0 C. If the fan impeller dimeter is 40 cm and the table tip air angle 20^0, determine the total pressure developed by the fan and the impeller width at exit. Take the radial velocity at the exit as 0.2 times the impeller tip speed. State the assumptions used.
A hydroelectric power plant uses Pelton-type turbines, in which multiple nozzles are used to accelerate the waterwhich is directed onto the turbine blades, which are exposed to an atmospheric pressure of 101.325 kPa. The water enters the nozzles with an absolute pressure of 500 kPa and a speed of 5 m/s, and the nozzle outlets are exposed to atmospheric pressure and have an internal diameter of 5 cm. Consider that the specific mass of water is 1,000 kg/m3.
Determine the mass flow rate of water through each of the nozzles, and explain why the actual mass flow rate will be lower.

The impeller of a centrifugal blower has a radius of 15 cm and a blade width of 6.1 cm at the inlet, and a radius of 30 cm and a blade width of 3.4 cm at the outlet. The blower delivers atmospheric air at 20°C and 95 kPa. Disregarding any losses and assuming the tangential components of air velocity at the inlet and the outlet to be equal to the impeller velocity at respective locations, determine the volumetric flow rate of air when the rotational speed of the shaft is 800 rpm and the power consumption of the blower is 120 W.
