Due to cavitation in pump suction.

When the water temperature is raised to 90 degrees the vapour pressure of the liquid. Increases so we have to raise NPSH are in order to make liquid pressure equal to or greater than VP of liquid. So we decrease the suction pipe length.

AT a 90 c temperature water is converted into the vapour phase so the centrifugal pump is used for transfer liquid and also cavitation is generated by a vapour through the impeller. So their fluid transfer capacity is reduced.
So, the Answer is 8.
So, the Answer is 8.
