A medium-size centrifugal air compressor has 32 radial blades and the inlet vanes allow air suction with no pre. whirl. The rotor speed is 7800 rpm and the tip radius is r2 = 0.25 m. Air is sucked in at a static temperature T1 = 305 K with an absolute velocity V1 = 80 m/s and a mass flow rate of 1.65 kg/s. The total-to total efficiency of the compressor is 80% and the power input factor is w =...

The flow in the impeller of a centrifugal pump is modeled by the superposition of a source flow and a free vortex flow. The impeller has an outer diameter of 0.5 m and an inner diameter of 0.3 m. At the outlet from the impeller, the flowing water has the following velocity components, relative to the impeller: radial component 1 m/s and tangential component 6 m/s. Determine! 1) the velocity potential and stream function for the superposition, the strength of...

Please answer question 7:
A centrifugal pump discharges 500 GPM through a 12-inch diameter
impeller. The fluid leaves the impeller with a
tangential velocity of 17 ft/sec. If water, @ 68°F,
enters the impeller via radial flow (I.E. no whirl), and the inner
radius and thickness of the impeller are
1.75-inches. (Assume a constant thickness of the
impeller) and if the pump speed is 1775 rpm, with a head loss of
4.5-feet. What is the horsepower input to the flow by
the pump?
