Oil Flows through a horizontal cylindrical pipeline with an average speed of 1.2 m/s. The pipeline has a radius of 0.5 metres. Calculate the volume of oil (in cubic metres) which flows through this pipeline in one hour.

Answer 1

pi r^2 = area = .25 pi = .785 m^2
area * speed = volume/second
.785 m^2 * 1.2 m/s = .942 m^3/s

times 3600 seconds /hr = 3393 m^3/hr
