Question

If oil flows out of a pipe at the speed of 2.65m/s and the diameter of the pipe is 5.0cm, determine the discharge rate?

Answer 1

radius of the pipe=$5/2=2.5cm=0.025m$

cross-section area of the pipe$=\pi r^2=3.142\times 0.025^2 =0.001964m^2$

discharge rate=speed of flow $\times$ cross-section area=$2.65\times 0.001964=0.005205m^3/s$
