The use of elbow or curved pipe in the installation of piping has a loss of pressure (pressure drop) which could lead the power of pump that drive the fluid and decrease the energy efficiency of the system. The pressure drop is caused by the curved shape ... see more

At the prerotation control there is an adjustable blade row before the pump impeller for producing a peripheral component of the inlet flow velocity. The effect of prerotation is changing along the H - Q characteristic and the range of control depends on ... see more

An Important problem in centrifugal pumps designing is characteristic works in theoretical calculations. They are precise or very close to practical characteristics and results of tests in laboratory. Hydrodynamics parameters influence on the inlet sides,... see more

Definition No reflow is a phenomenon in which myocardial ischemia and reduced antegrade flow occur despite the absence of proximal stenosis, spasm, dissection, or embolic cut off of major distal branches.1 In another word no reflow phenomenon means failur... see more
