7 Dynamic Similitude
282
always somewhat lower than the design flow rate. With the flow rate at the design
operating point estimated at 10 % higher than at optimum efficiency, the estimated
design flow rate is 0.80 m
3
/s. The corresponding interpolated value of the total pressure rise is 3470 Pa. The obtained values of flow rate and total pressure rise are very
near to the target values.
