A natural-gas pipeline with a diameter of 0.250 m delivers 1.55 m^3 of gas per second. What is the flow speed of the gas

Answered by maham237 @ 28/04/2021

First, let's calculate the cross-section of the pipeline. The radius of the tube is half the diameter:
$r= \frac{0.250 m}{2}=0.125 m$
And the cross-sectional area is:
$A= \pi r^2 = \pi (0.125 m)^2 =0.049 m^2$

The volumetric flow rate is $\rho = 1.55m^3 /s$ . If we divide this value by the cross-sectional area of the pipeline, we get the flow speed of the gas:
$v= \frac{\rho}{A}= \frac{1.55 m^3}{0.049 m^2}=31.6 m/s$
