  3. 1 天前 · Thank you sm. Replies continue below. LittleInch (Petroleum) 28 May 24 11:16. In series, the flow is the same in both pumps..... so Flow 1 = Flow 2. (Conservations of mass etc) Then add the differential head at the SAME flowrate. you cannot have two different flow rates so (a+a)/2 = a.... So e.g. pump 1 at 10m3/hr has an outlet head of 50m.

    18 小時前 · The centipoise is convenient because the viscosity of water at 20 C is about 1 cP, and one centipoise is equal to the SI millipascal second (mPa·s). The SI unit of kinematic viscosity is square meter per second (m 2 /s), whereas the CGS unit for kinematic viscosity is the stokes (St, or cm 2 ·s −1 = 0.0001 m 2 ·s −1 ), named after Sir George Gabriel Stokes .
