Question

A Centrifugal pump is used to transfer a volatile organic solvent (SG = .9 , mu = .003 Pa*s) from a remote storage tank to an exraction column. The pump requires NPSH of 5 m. The solvent level in the storage tank is maintained at 2 m above the pump inlet. The solvent flows at 45 kg/s through 16 cm smooth pipe. The solvent has a vapor pressure of 26.7 kPa and the pressure in the storage tank is atmospheric.

What is the maximum distance from the stoage tank that the pump can be located without the danger of cavitation?
