The overall efficiency of a centrifugal pump is simply the ratio of the water (output). power to the shaft (input) power and is illustrated by the equation below. Î· = P W / P S where Î· is efficiency, P w is the water power, and P s is the shaft power.
While talking about difference between a ship and a boat, the first thing that comes to oneâs mind is their sizes. Traditionally people consider a ship as a large ocean going vessel, whereas boats are comparatively quite smaller in size.
A naval ship is a military ship (or sometimes boat, depending on classification) used by a navy.
