Answer to Question #177030 in Physics for Lawrence

Question

cylinder of height 30cm filled to a height of 20cm with water and the rest occupied by kerosene given that density of water is 1000 kg/m3 and density of kerosene is 800kg/m3 and atmospheric is 103,000 pascal determine the pressure acting on the base of the container

Answer 1

The pressure acting on the base of the container is the result of pressure of water, kerosene, and air:

$$p=p_w+p_c+p_a,\\ p=\rho_wgh_w+\rho_cgh_c+p_a,\\ p=105744\text{ Pa}.$$
