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 boat is a watercraft of a large range of sizes designed to float, plane, work or travel on water. Small boats are typically found on inland waterways or in protected coastal areas. However, boats such as the whaleboat were designed for operation as a ship in an offshore environment. In modern naval terms, a boat is a vessel small enough to be carried aboard another vessel. An older tradition is that a ship has a weather deck fully enclosing the hull space, while a boat lacks a full weather dec
