A numerical example is the best way to understand how to use the HazenWilliams equation to determine the velocity and flow of water. Multiply the value from step 2 with the density of water and divide by 2. : The potential energy density is calculated with the use of a modified potential energy equation, with density instead of mass of the fluid. To calculate the hydraulic radius RRR, divide the cross-sectional area (A=r2) (A = \pi \cdot r^2)(A=r2) of the pipe by the wetted perimeter (P=2r)(P = 2 \cdot \pi \cdot r)(P=2r): In the Advanced mode of the pipe flow calculator, you can find or input other parameters such as area, perimeter, hydraulic radius, and the slope. In contrast to DarcyWeisbach's equation, HazenWilliams has the advantage that it doesn't require an iterative calculation or guessing the friction factor or Reynolds' number. Use our pipe flow calculator to determine the velocity and flow rate of water that flows by gravity. WebThe following equation can be used to calculate the pipe velocity: Components of the Equation V = Water velocity inside the pipe (m/second) Q = Volume flow (m/second) D = Pipe inside diameter (inner diameter) (m) PIPE VELOCITY CALCULATOR VARIABLES: Pipe Diameter and Water Flow Rate The water flow rate / The pipe diameter Water The formula is v = k * C * R0.63 * S0.54. Before going further, let us first try to understand what Bernoulli's equation is. FAQs on Pipe Flow Calculator 1.
