Water flows at 10 m/min through a pipe of radius 7 cm into a conical tank of base radius 1 m and height 2 m, initially empty. How many minutes are needed to fill the conical tank completely? (Use π = 22/7)

Question

Accepted Answer

About 13.6 min. Tank volume = 1/3(22/7)(1^2)(2) = 44/21 m^3 = 2.0952 m^3. Pipe area = (22/7)(0.07^2) = 0.0154 m^2; flow rate = 0.0154 x 10 = 0.154 m^3/min. Time = 2.0952/0.154 = 13.6 min.
