**Damon**, Wednesday, April 16, 2008 at 9:11pmThe pressure is determined by the height of water in the tank.

P = rho g h

rho is about 1000 kg/m^3

g is 9.81

P is 50 *10^3 Pascals

solve for h in meters

then the radius of the tank is 4.3 meters and it is filled to depth h

volume of water = (1/6) pi h (3 rh^2 +h^2)

where rh is the radius at the water surface with depth h so rh = sqrt (2Rh-h^2)

then convert those m^3 to liters
