    HEAT EXCHANGER SYSTEM CURVE

    Perhaps I missed this class while in college ... I understand that the actual pumping capacity (and head) is the result of intersection between pump curve and system curve. there is a pump supplying cold water for a typical heat exchanger process (cooling). By the ampere meter reading, we can...

    Fitting distance from Pump

    I read from a pump manual that we should be avoid any fittings, including bends, compensators, valves in the area of 5 X DN suction and 5 X DN discharge. I guess if before suction, the fitting will make the flow less smooth and can make cavitation. But what is the purpose of this 5 x DN? Thanks...

    Unpumpables

    Hi there, What is the definition of Unpumpable? I mean, what is the limitation of a fluid to be determined as "unpumpable". A piston pump like Putzmeister can pump the solid. Or in the Hidrostal brochure they said that they can pump fresh fish. What can be pumped, what can not be? Do...
