Q 5. A pump is needed to pump water at a rate of \( 0.2 \mathrm{~m}^{3} / \mathrm{s} \) from the lower to the upper reservoir shown in the figure. What will be the NPSH of this pump if the impeller speed is to be \( 600 \mathrm{rpm} \) ? Assume \( \mathrm{f}=0.02 \) and \( \mathrm{K}_{\mathrm{c}}=0.5 \), Temperature \( 25^{\circ} \), pump elevation \( =10 \mathrm{~m} \) and length of pipe at the inlet side \( =8 \mathrm{~m} \).
