WebMar 5, 2024 · The flow rate can be determined by. ˙Q = 2πrUr. Where ˙Q is the volumetric flow rate, r is distance from the origin and Ur is the velocity pointing out or into the origin depending whether origin has source or sink. The relationship between the potential function to velocity dictates that. ∇ϕ = UU = Uˆr = ˙Q 2πr ˆr. http://web.mit.edu/16.unified/www/FALL/fluids/Lectures/f15.pdf
