Fluids Question
Consider a centrifugal blower that has a radius of 20 cm and a blade width of 8.2 cm at the impeller inlet and a radius of 45 cm and a blade width of 5.6 cm at the outlet, the blower delivers air at a rate of 0.70 m3/s at a rotational speed of 700 RPM. Assuming the air enters the impeller in the radial direction and exits at an angle of 50° from the radial direction, determine the minimum power consumption of the blower, take the density of the air to be 1.25 kg/m3 (ans 152W)
