These are called the pump curves. They are determined by studies, whose methodology is standardized. These curves are specified when water is pumped with a density of 1000 kg/m3 and kinematic viscosity of 1 mm2/s. When the circulating pump is used for liquids of different density and viscosity, the pump curves have to be recalculated.
EGR valve the top of box on top of the inlet manifold of a Saab H engine in a 1987 Saab 90. In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1]
If a pump forces the liquid through a tube connected to a system consisting of a Venturi to increase the liquid speed (the diameter decreases), a short piece of tube with a small hole in it, and last a Venturi that decreases speed (so the pipe gets wider again), the gas will be sucked in through the small hole because of changes in pressure.
Reciprocating pump has wide application and to clear the basic idea it is necessary to know the basic parts. The basic parts along with its function; Water reservoir - it is not a part of reciprocating pump, however, it is the main source where from the reciprocating pump takes the water. It may be a source of other fluid as well.
This is due to the electrical requirements of the pump forcing circulation and the amount of water being circulated through the tubes. [ 6 ] The additional parts required; steam drum, circulation pump, and orifices to limit flow, cause a forced circulation boiler to lead to increased cost as well as increased opportunities for failure which ...

Water circulation is aided by a rotary pump that has only a slight effect, having to work over such a wide range of speeds that its impeller has only a minimal effect as a pump. While running the leaking pump seal drained cooling water to a level where the pump could no longer return water to the top of the radiator, so water circulation ceased ...
