Question

48
Water flows at the rate of 10 m per minute through a cylindrical pipe having diameter
g0 mm. How much time will it take to fill a conical vessel of base diameter 40 cm and
depth 24 cm?​

Answer 1

hey mate

SolutionVolume flown = 1/3 PI (20)^2 * 24 = 3200 Pi

Volume flown in 1 min = (Pi* 2.5/10 * 2.5/10 * 1000) = 62.5 Pi

Therefore Time taken = 3200 Pi / 62.5 Pi = 51 min. 12 sec.
