Question

a 2,4 high container in a chemical plant stores three separate chemicals ,one on top of each other .These chemicals have densities of 1450 kg/m^3,550kg/m^3 respectively. Each chemical has a height of 0,8 m. Determine the total force on the 1,5 m side of the container and where it acts

Answer 1

$F=PA$

$A=S^2=1.5^2=2.25m^2$

$P=P_1+P_2+P_3$

$P=\rho_1h_1g+\rho_2h_2g+\rho_3h_3g=9.8(1450*2.4+550*1.6+200*0.8)=44296Nm$

$F=44296 *2.25=99666N$

The force acts on the bottom side of the container.
