The performance curve of a pump at 1800 rpm is well represented by the quadratic equation:

where H (m) is the total head, and Q (Lsí1 ) is the flow rate.

(a) Obtain the performance curve at 2000 rpm. (b) This pump is installed in a pipe network with a system curve given by the equation:

where H is the head loss in m and Q is the water flow rate in m3 s í1 . Obtain the water flow rate and the ideal power input when the pump speed is 1800 rpm and 2000 rpm
