TrevorP Fluid B batche is 107000 bbl; Fluid A batche is 125000 bbl; the capacity of pipeline is 117500 bbl. Fluid B is pumped by screw pumps and fluid A by centrifugal pumps.

Fluid A is 150 cSt, 0.94 s.g. Fluid B is 300 cSt, 1.015 s.g. Fluids are homogenized.

Could somebody help me about the hydraulic analisis for transportation in a pipeline of two liquids with differente viscosity. That liquids are transported in batches separated by pig. What viscosity must I consider? Pipeline is 200 miles lenght.

Its known that in a positive displacement pump suction line must be take in account the acceleration head (ha)and substract it for the NPSHA. But, what is the value of NPSHA for comparison with NPSHR. NPSHA = Pa+Hs-Pv-hf-ha? or NPSHA = Pa+Hs-Pv-hf? Why? Thanks Ciro
