Webb2 okt. 2015 · Assuming laminar flow, the Hagen–Poiseuille equation defines the flow rate as a function of the head pressure. However as the flow rate increases so does the head loss due to friction within a pipe, as stated by the Darcy-Weisbach equation.
WebbAnalysis of the flow line in Figure 1 shows that the water flow has diffluent rates in the horizontal and vertical directions and belongs to the plane two-dimensional flow. If the Dupuit assumption can be introduced and the vertical diffluent rate is neglected, the calculation can be simplified to a one-dimensional flow calculation in the x direction [ 32 ]. cycloplegic mechanism of actionWebbUsing the equation for the mass flow rate to determine the velocity at point 2: m ˙ 2 = ρ A 2 v 2. v 2 = m ˙ 2 ρ A 2. v 2 = 8000 lbm hr ( 62.4 lbm ft 3) ( 0.2006 ft 2) v 2 = 639 ft hr ( 1 hr 3600 sec) v 2 = 0.178 ft sec.
