Question

a pipe of diameter 0.036 m discharge water at a rate of 1.6 m/s into a cylindrical tank with a base radius of 3.4 m and a height of 1.4 m. find the time required to fill the tank, giving your answer correct to the nearest minute.​

Answer 1

answer

circumference of the pipe

pi*diamater:which is 3.142*64m=201.88mm

the pipe discharges 2.05mm of water per second, so volume of warter to tank per second then the volume of tank is

v=pi*r^2=3.142*3900mm^2*23000=109910000 to find time

1sec =412.2304mm^3

109910000/412.2304

=26638.51

rounding off we get

=266638sec
