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 mast is something that pushes the boat with wind and the reason its called a mast is cause it holds the biggest sail, the thing your looking for is something that is on the bottom of the boat and runs vertical on the boat. if that gets ruined the boat is ruined, unrepairable. Robbie Grabowski.
