A pump can lift water at a discharge rate of 0.15 m3/sec to a head of 25 m in a 1 m diameter pipe. The critical cavitation number is 0.13. The barometer reads 10 m of water at the pump location of the vapour pressure of water is 0.3 m of water. Friction loss in the pipe can be taken as 0.2×Velocity head(\(\frac{v^2}{2g}\)). Find the maximum allowable elevation above the sump water surface at which the pump can be located. (Round off to two decimal places)
