Problem

A cylindrical paint bucket of radius R=15  cmR = 15\;\text{cm} has a small circular hole of radius r=2.0  mmr = 2.0\;\text{mm} drilled near the bottom. The bucket is initially filled with paint to a height h0=40  cmh_0 = 40\;\text{cm} above the hole. The paint has density ρ=1200  kg/m3\rho = 1200\;\text{kg/m}^3 and flows like an ideal fluid. As the paint drains through the hole, the height of paint in the bucket decreases over time. Find the time tt required for the paint level to drop from the initial height h0h_0 to half that height, h0/2h_0/2. Take g=10  m/s2g = 10\;\text{m/s}^2.
