WebA = the cross sectional area of flow. V = the mean velocity . Calculation of flow rate is often complicated by the interdependence between flow rate and friction loss. Each affects the other and often these problems need to be solved iteratively. Once flow and depth are know the continuity equation is used to calculate velocity in the culvert. WebJan 23, 2016 · Consider a continuous stream of water flowing down from a tap. Since the water flow is continuous, by equation of continuity, the cross sectional area of the stream decreases. But what makes the water flow sideways, ie, which force is responsible for decreasing the area of cross-section?
WebThe rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels. As the total cross-sectional area of the vessels increases, the velocity of flow decreases. Blood flow is … WebA = cross-sectional area of flow in square feet R = hydraulic radius in feet (equals the area of the flow divided by the wetted perimeter) S = slope of pipe line in feet of vertical drop Metal Pipe per foot of horizontal distance Since the designer is usually concerned with selecting a sewer size for a given design flow and pipe
WebA 6.0-foot-wide rectangular channel has a normal depth of 2.45 feet, (a) What is the cross-sectional area of the flow? (b) What is the wetted perimeter? (c) What is the hydraulic radius? A channel conveys a discharge of 210 cfs at a velocity of 5.45ft/s. Find the cross-sectional area of the channel. Refer to the following channel cross section. WebEstimate the type of flow in a channel having cross sectional area of 50m² and top of the channel is 5m. The mean velocity of flow is 0.1m/s and the absolute viscosity of water is 0.625 N-s/m². The wetted area of a most economical trapezoidal section is 21.58m², base width of 5m and side slope of 1H:3V.
