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.
Close. Sailboats differ from other types of boats in that they are propelled partly or entirely by wind; they use sails to transform the power of the wind into power that moves the boat through the water. The term sailboat covers a wide variety of sailing craft, each with its own characteristics and styles.
