Question
A tank of height 5 m is full of water. There is a hole of cross sectional area 1 cm2 in its bottom. The initial volume of water that will come out from this hole per second is : -
Options
A.10-3 m3/s
B.10-4 m3/s
C.10 m3/s
D.10-2 m3/s
Solution
Velocity of efflux
= 10m/s
rate of flow
= Av = (1 × 10-4) × 10 = 10-3 m3/s
= 10m/srate of flow
= Av = (1 × 10-4) × 10 = 10-3 m3/s
