Answer:
Diameter of pipe = D = 64mm
cross sectional Area of pipe= A = pi * (D/2)^2 = pi * (32)^2 = 1024pi mm^2
Discharge Rate of water = v = 2.05 mm/s
Volume of Cylinder = V = pi * (D/2)^2 * h = pi * (38)^2 * 2300 = 3321200pi mm^3
(Area of pipe)*(Rate) = (Volume) / (Time)
Time = T = (Volume) / [(Area of pipe)*(Rate)]
= (3321200pi)/(1024pi * 2.05)
= 1582.126524s
Chance of getting 4 heads in a row is (1/2)^4=1/16. So it should take 16 tries to likely get 4 heads in a row. Now to find amount of coin tosses it would be 16 x 4 = 64 coin tosses.
