    Stainless steel pipe selection

    dear friends i have an application for pumping system it consists of 3 parallel pumps having a max head of 8 bars i have a stainless steel pipe has 8" diameter and sch 10 will this be suitable to be used under this pressure ?

    How to study this kind of flow ?

    boneh3ad i know the NSE can be applied to all systems on the earth but here how can we apply it ?? in cartisian co-ord. or we will use the polar co-ord. and in the redius direction or in the angel direction i think its complicated , i have studied this case and get an equation for flow using the...

    Hydraulic total pressure

    my friend we always here neglect secondary losses like fittings and valves but length no and also it depends on the length ur talkin abt

    Hydraulic total pressure

    because u give the pump electric power and it transimits it to hydraulic power thats the reason YURI

    Damn centrifugal pump

    i am very sorry for unclear description but the original pump in the manual was 2.2 kw has q=12m3/hr and H = 20 m the new pump they put is 10hp q=20m3/hr and H= 40 m and while its operatin on the machine it gives 25 meter head only not 40 the sitiuation now is that i have searched for these...

    Damn centrifugal pump

    accordin to my last to posts here i found this special pump which has materials designed to carry a high press but the problem now i found a pump on the machine is bigger than the one in the manual so shall i buy the pump from manual or as the existing pump ?

    Pump question

    yes ur very right u know the pump has high Hms and Hmd but normal Hm and the pump will give speed to water yes correct i think its an ordinary pump not special pump because these 10 bars after operating the pump it will reduced by the value of vacum created by pump impeller do u faced...

    Pump question

    so the pump is a normal pump ???

    Pump question

    tell me guys whats the relation between Hms and Hmd and the pump selection for example i have Hms =10bar , Hmd =12 bars so Hm =2 bars so the Head of the pump is only 2 bars or its said that pump has a head of 2 bars and can withstand 12bars ???

    Pressurized centrifugal pump

    thanx edgepflow so the pump selection will be a normal pump but the materials of casing and impeller should withstand this high pressure
