Fluid mechanics head loss equation
WebIn fluid mechanics, pressure head is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column on the base of its container. It may also be called static pressure head or simply static head (but not static head pressure).. Mathematically this is expressed as: = = where is pressure head (which is actually a … WebApr 13, 2015 · This thermal energy cannot be converted back to hydraulic energy, so the fluid experiences a drop in pressure. This conversion and loss of energy is known as head loss. The head loss in a pipeline with Newtonian fluids can be determined using the Darcy equation (Equation 1). Where: h L = Head loss (feet of fluid) f = Darcy friction factor ...
