Centrifugal Pump & Priming


Centrifugal pump is a radial flow pump which works on the roto-dynamic principle. It's a low pressure pump. The rotating component is impeller which imparts rotational energy to the liquid. Volute casing converts this energy into pressure energy. Discharge pressure is increased by fitting a diffuser. It is useful in a system where a high volume liquid flow is needed. 
Unlike positive displacement pump, it is not self priming pump. To remove air from the suction pipe and allow liquid to flow into the pump a water ring primer is coupled to the pump.

Stiff ship and tender ship     STIFF SHIP When a metacentric height and righting lever distance is large, Ship have excessive stability Ship will come to its normal upright position very quickly when its heeled. Tender ship When metacentric height and righting lever distance is very small.  Ships have less stability Ship will come to its  normal  upright position very slowly when its heeled.
