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.
Truth. The main physical difference between a pontoon and a deck boat is the shape and function of the hull. Deck boats typically have a V-shaped hull, while pontoons lie flat on the water with the deck balanced on two or three hollow aluminum tubes. The V-shaped hull on deck boats enables the boat to cut through the water and get up on plane at a high speed, creating a surf able wake.
