A dike in Holland springs a leak through a hole of area 0.80 cm2 at a depth of 1.2 m below the water surface.
How much force must a boy apply to the hole with his thumb to stop the leak?
Answered by Damon
pressure = rho g h
= 1000 kg/m^3 * 9.81 * 1.2

Force = pressure * area
= 1000 * 9.81 cm^2/m^2 *1.2 * .8 /(10,000cm^2/m^2)
