Design discharge of canal formula
WebFeb 27, 2024 · Is it possible to сalculate discharge / flow rate on the pipe diameter and the pressure (for constant pressure)? For example: Pressure_internal = 5 bar, Diameter_pipe = 36 mm, Density_water = … Webflow rate in the channel, also known as discharge, is based on the continuity of flow equation or Equation 4-1. This equation states that the discharge (Q) is equivalent to the product of the channel velocity (V) and the area of flow (A). Q = V A (4-1) Where: Q = discharge, cfs V = velocity, ft/s A = flow area, ft. 2
