1-For a flexible impeller,Calculate the change in static head H_s given the outlet and inlet pressures are 2.42 and -0.81 kPa with 988.2 kg/m³ water density

2-Given H_t = H_s which is found in part 1. If the flowrate is 0.00132 m³/s, calculate the hydraulic power (P_h) in watt

3-Calculate the mechanical power in watt using Equation (5) given that the rotational speed (N) is 2804 and the torque is 0.961 N.m

4-Calculate the overall efficiency by Equation (6) using the information found in the previous parts. (write the number without % symbol)

5-Calculate the volumetric efficiency using Equation (11) given the actual and ideal flowrates are 0.00132 and 0.00249 m³/s, respectively. (write the number without %)

The volumetric efficiency of the pump can be calculated as: Ev=QidealQ100 Vth for the C3-MKII-21 Gear pump is typically 1.7143107m3/s/rev Vth for the C3-MKII-23 Flexible Impeller pump is typically 8.888107m3/s/rev Eo=PmPh100 where, Ph= hydraulic power imparted to fluid =gQHt Q= volumetric flow rate Pm=602NT
