Web22. Dez. 2024 · For flow through natural features, such as a riverbed, you have to approximate the area. Assume the deepest part of the river to be the radius of a semi-cylindrical trough. Calculate the cross-sectional area using π r 2, then take half of that and use that for A in the equation Q = v × A to get an approximate flow rate. WebThe volume flow rate is Q = d V d t = A v, where A is the cross-sectional area of the pipe and v is the magnitude of the velocity. The precise relationship between flow rate Q and average speed v is Q = A v, where A is the cross-sectional area and v is the average speed.
