Here ,
V = pi * r^2 * h/3
a) volume of the water = pi * 15^2 * 25/3
volume of the water = 5889 cm^3
the volume of the water is 5889 cm^3
weight of water = V * density * g
weight of water = 5889 * 1/1000 * 9.8
weight of water = 57.7 N
b)
force on the base of vessel = pressure * area
force on the base of vessel = 1000 * 9.8 * 0.25 * pi * 0.15^2
force on the base of vessel = 173 N
the force on the base of the vessel is 173 N
this is greater than weight of water as the walls of the container also applies a force downwards on the water.

A conical tank of radius R and height H, pointed end down, is
full of water. A small hole of radius r is opened at the bottom of
the tank, with r, much much less than, R so that the tank drains
slowly. Find an expression for the time T it takes to drain the
tank completely.
Hint 1: use Bernoulli’s equation to relate the flow speed from
the hole to the height of the water in the cone.
