Question

(g) Water is flowing through a circular channel at 8 m/s. Find the number of m*2

discharged per minute if the channel, always full, has a radius of 8 cm.​

Answer 1

Below

Explanation:

( Your question asks for m^2 discharge......I think you need m^3 discharge per minute)

Find the volume of a cylinder that is 8 meters long with radius of 8cm ( .08 m)

area = pi r^2 = pi (.08)^2 = .0201 m^2

area * 8 m = volume PER SECOND

volume PER SECOND * 60 = volume per minute

.0201 * 8 * 60 = 9.65 m^3 / min discharge
