(a) A pump is lo be located at a place where the baromeltic pressure is 98 kPa (abs). The pump has to deliver $0.15 \mathrm{~m}^{3}$ of water against 30 m head. The vapour pressure is 3 kPa (abs) and the crilical cavitalion number of the pump is 0.1 . Assuming pipe friction to be equivalent to 0.025 , find the minimum value of NPSH and the maximum allowable elevation above the sump.
Explanation
To find the minimum NPSH, we need to calculate the atmospheric pressure head, the vapor pressure head, and the velocity head. The maximum allowable elevation is then calculated by subtracting the vapor pressure head from the atmospheric pressure head.
