Impeller diameter at the entrance of the impellers is 32 mm in a homologuous series centrifugal pumps. Impeller diameters are 210, 240 and 264 mm. Liquid leaves impeller by making an angle with tangent as 30° (t/6 radian). The rotational speed of the impellers are 1450 rpm (revaluation/ min). a) Calculate the required power of the pumps if the volumetric flow rate of water transported is 10 m/h, b) How power requirement of the pumps change if the volumetric flow rate of water transported is increased to 20 m/h.
