1. The problem statement, all variables and given/known data On January 15, 1919, a cylindrical tank of molasses ruptured, and poured out over the streets of Boston in a 9 m deep stream. Pedestrians and horses were killed, and buildings were knocked down. Suppose the tank was 87.7 m high and 3.37 m diameter, and it was full of molasses (density 1630 kg/m3). Find the total force exerted by the molasses on the inside of the tank before it broke. 2. Relevant equations P=F/A P=ρgh pressure of air 1.103x10^5 use Greek letter ϕ A is the area ρ is density d is diameter 3. The attempt at a solution since the pressure changes, i think i should integrate to find force. ΔF=P∙ΔA=∫(ϕ+ρgh)πd∙Δh after integrate i get : F=ϕπdH+(ρgπdH^2)/2 it's right?
