Question

A cylindrical vessel of radius R and height H and open at the top is completely filled with water. A small circular hole of radius r is made near the bottom of vessel. The time taken for 25 % of water to flow out is, 2 H g 3 - 1, R 2 r 2 2 H g 1 + 2 3, R 2 r 2 2 H g 1 - 3 2, r 2 R 2 2 H g 3 - 1

T = A a 2 H g = R 2 r 2 2 H g t 1 = R 2 r 2 2 g × 3 H 4 ∴ Δ t = T - t 1 = R 2 r 2 2 H g 1 - 3 2
