volume of tank = pie (1.4/2)^2 × 2.1
= pie 0.49 × 2.1
= 3.23
volume of water flowing per second = pie (3.5/200)^2 2
= 3.14 × 12.25/40000 × 2
= 0.0019
So time in which tank will be filled = 3.23/0.0019
= 1700 sec
= 28.3 minutes
= pie 0.49 × 2.1
= 3.23
volume of water flowing per second = pie (3.5/200)^2 2
