    Pumping Warm Crude Oil: Calculating NPSA & Velocity Head

    Thanks Fred, I reworked my solution to the velocity head and got an answer of 0.02281m also.. Converting my u value to m3/hr involved 4000/846 then multiplying by 3600 and the area

    Pumping Warm Crude Oil: Calculating NPSA & Velocity Head

    So the Head loss in the suction line will be the frictional head loss which is the 1.2m value given in the question.. Also The formula is H(v) = u^2/2g [where u = Q/pi*r^2] Therefore when calculating Q, i must divide by 3600 and also multiply by radius squared and Pi and After converting...

    Calculating Pressure Drop Across Valve in Horizontal Pipe

    Hi, 20m straight length horizontal pipe (60 mm internal diameter), steam flows at rate 0.5 kg/s, at midpoint there is a valve in the line. inlet pressure to this section of line is 5 bar (gauge), pressure at end of line is 3 bar (gauge). mass quality of steam is 0.8 and 2 phase flow occurs in...

    Pumping Warm Crude Oil: Calculating NPSA & Velocity Head

    At an oil refinery, a mobile centrifugal pump is used to pump warm crude oil from a storage tank. Liquid level in tank at elevation of 3 metres above pump. Suction side of pump is fed with a flexible hose that is 10 metres long. Crude oil density: 846 kg/m3 Crude flow 4000 kg/h Internal...
