Fluid properties affecting pumps

WebA positive displacement pump has a phenomenon known as “slip,” which is the recirculation of the pumped fluid from the discharge side of the pump back to the suction side of the pump. The amount of slip is affected by the system discharge pressure requirement and the fluid viscosity. As the discharge pressure increases, it will force more ... WebAug 26, 2024 · Fluids are pumped at elevated temperatures for a number of reasons: The fluid needs to be heated to change it from a solid or semi-solid into a liquid so it can be more easily moved, processed or applied. A process where heat is used as a catalyst to initiate or sustain a chemical reaction.

WebIn the absence of an internal source, when the fluid is in contact with a hot surface, its molecules separate and scatter, causing the fluid to be less dense. As a consequence, the fluid is displaced while the cooler fluid gets denser and the fluid sinks. Thus, the hotter volume transfers heat towards the cooler volume of that fluid.
