WitrynaΔp = pressure loss [Pa] L = the length of the pipe [m] fD = Darcy friction factor [unitless] ρ = fluid density [kg/m3] v = mean fluid velocity [m/s] D = pipe diameter (or hydraulic diameter for non-circular ducts) [m] Sometimes it may be more convenient to express the pressure loss per length of pipe. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases. A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reache… WitrynaThe head loss coefficient of the restricted orifice decreases with the increase of cross-sectional area of the restricted orifice and increases with the increase of split ratio. When the split ratio is 1, all water flows into the surge tank, and the head loss coefficient is the largest, which is 13.32, 11.77 and 8.66 jessica wong rf cuny
