The axial flow pump produces a discharge of 0.055 m3/s. (Figure 1) The impeller is rotating at ω = 70 rad/s, and it has a mean radius of 75 mm. The diameter of the impeller's shaft is 100 mm.
Determine the magnitude of the velocity of the water as it exits the blades.
Determine the magnitude of the relative velocity of the water as it flows off the blades of the impeller.
A pump is delivering 160 liters per second of water using an impeller diameter of 254mm and operating at a speed of 1800 rpm. If the speed is held constant and the impeller diameter is changed to 203.2 mm, what is the new discharged of the pump in liters per second?(128 L/s)
A single-stage centrifugal pump has an impeller speed of 1750 rpm. If the flow rate of water is 60 gal/min, determine the expected head.
