1. A pump when tested at \( 1200 \mathrm{rpm} \) gave the following data: The pump is used to deliver water through a pipe system which is of uniform diameter of \( 90 \mathrm{~mm} \) and for which the friction loss may be taken to be equal to \( 5 \frac{v^{2}}{2 g} \) where \( v^{2} \) is the velocity in the pipe. The static lift is \( 6 \mathrm{~m} \). Determine the flowrate and developed head of the pump.
