diameter does not matter
p = density * g * depth
(the weight of water in a 1 m^2 column)
so
water weighs 1000 kg/m*3
so we are talking a mass of 1000 * 20
20,000 * 9.81 = 196,200 or 1.96*10^5 Newtons/m^2 or Pascals
HOWEVER on to of that you have the air pressure which is about 10^5 Pascals
so for total pressure about 2.96*10^5 Pascals
A 30m high cylindrical water tank has a diameter of 14m. The tank is two-thirds full of water. What is the pressure at the bottom of the tank?
