Question
Centrifugal pump has differential pressure 15 bar and use to transport oil between two separators. If the
pressure at first separator is 4 bar calculate the pressure at second separator and NPSH.
Where:
Suction and discharge pipe diameters = 10 inch,
Suction pipe length = 16 m, ld
Oil level at first separator 3 m2d
Oil density=880 kg/m³ P
Oil flow rate=0.092 m³/sec
e
Pipe roughness= 0.045 mm
Discharge pipe length = 25 m O
Oil level at second separator = 5.5 m2d
Oil viscosity = 9.5 x 10³ Pa.s
Oil vapor pressure 22.5 kPa
