A centrifugal pump is to be placed above a large, open water tank, as shown in Figure Q5 (c), and is to pump water at a rate of. At this flowrate the required net positive suction head, is \( 15 \mathrm{~m} \), as specified by the pump manufacturer. The water temperature is \( 80^{\circ} \mathrm{C} \) and atmospheric pressure is \( 1 \mathrm{~atm} \). Assume that the major head loss between the tank and the pump inlet is due to filter at the pipe inlet having a minor loss coefficient \( \mathrm{K}_{\mathrm{L}}=20 \). Other losses can be neglected. The pipe on the suction side of the pump has a diameter of \( 4 \mathrm{~mm} \). Determine the maximum height, that the pump can be located above the water surface without cavitation. (10 marks)
