A tank full of water has a small hole at its bottom. Let t, be the time taken to empty the first half of the tank and t2 be the time needed to empty the rest half of the tank, then
t1 = t2
t1 < t2
t1 > t2
t1 = 0.523t2
Initially due to more pressure at the hole, velocity of efflux will be more. So, the liquid drain out more quickly.
Hence, t1 will be less than t2 .
