1.Water at 40°C is stored in an open tank at atmospheric pressure. The pump is 3.0 m below the open tank level. The velocity in the pipe is 1.5 m/s. The friction head loss in the pipe has been calculated as 2 m. The required (NPSH)R for this pump is 3.0 m. Calculate the available (NPSH)A.

2. Calculate (NPSH)A according to the figure given below. (density of the fluid=1514 kg/m3)
