Water at 40 °C is pumped from an open tank through 200 m of 50 mm diameter smooth horizontal pipe as shown in figure (a) of the system and discharges into the atmosphere with a velocity of 3 m/s. Minor losses are negligible. T 3 m 1 a) If the efficiency of the pump is 70%, how much power is being supplied to the pump? What is the NPSHA at the pump inlet? Would you expect cavitation in the pump to be a problem? Explain using the pump performance characteristics shown in figure (b).

A cranking compression test i did gave the following results i had 155 psi in cylinder 1 and 140 psi in cylinder 2 and ihad 145 psi in cylinder 3 and i had 105 psi in cylinder 4. Would it be a burnt intake valve or a defective head gasket?
