Type 63 - Basic amphibious light tank with half-egg-shape turret, armed with 85 mm Type 62-85TC rifled gun and powered by the 6-cylinder 4-stroke inline water-cooled diesel engine developing 240 hp (179 kW) at 1800 rpm from the Type 60 amphibious light tank. It entered service in 1963 and produced in small numbers.
The FW was designed in response to the British Government's Ministry of Defence (MoD) requisition outline issued in 1950, specifying a water pump and petrol engine combination to deliver 350 gallons of water per minute at 100 psi, with 35 to 40 bhp at the weight of 350 pounds or less. The successful bid by a portable pump driven by the 38 bhp ...
A water-returning engine was an early form of stationary steam engine, developed at the start of the Industrial Revolution in the middle of the 18th century. The first beam engines did not generate power by rotating a shaft but were developed as water pumps, mostly for draining mines.

The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
The largest possible design of a water engine is the directly acting water-column engine or water column machine [3] (German: Wassersäulenmaschine). Such devices had been in use for pumping purposes in different mining areas since the middle of the eighteenth century and one was used, for example, by Georg Friedrich von Reichenbach in 1810 to ...
This is particularly so in tropical countries where warmer water means the plants grow more quickly, and increasing run-off of fertilisers and effluent has exacerbated the problem. Irrigation ditches and pumps can become overgrown with vegetation, power station and factory water intakes can get blocked, boats can get hindered, fish stocks can ...
A rotodynamic pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor, in contrast to a positive-displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge.
