Web16 Nov 2024 · This is because higher velocities can cause pipe erosion, increase noise, and potentially lead to pressure drops. While specific requirements may vary based on factors such as pipe material, pressure, and fluid properties, it is generally recommended to maintain a flow velocity of no more than 8 ft/s in residential areas. Web2 Mar 2024 · TW = tailwater depth, m (ft) g = acceleration due to gravity, 9.81 m/s 2 (32.2 ft/s 2) Tailwater depth for Equation 10.4 should be limited to between 0.4D and 1.0D. If tailwater is unknown, use 0.4D. Whenever the flow is supercritical in the culvert, the culvert diameter is adjusted as follows: gig harbor washington lodging
