Fluid mechanics head equation
WebApr 13, 2015 · The example below uses Equation 2 to calculate head loss in a 100-foot section of a 4-inch, schedule 40 steel pipe with a flow rate of 400 gallons per minute (gpm). The calculation shows a head loss of 8.46 feet of fluid. Next, we will determine what happens when the flow rate is changed. WebThe most common equation used to calculate major head losses in a tube or duct is the Darcy–Weisbach equation(head loss form). where: Δh = the head loss due to friction …
