The first step is to convert the gage pressure to absolute pressure by adding the atmospheric pressure. - 28 inches of mercury can be converted to psi by dividing by 2.036, which equals 13.74 psi. - Adding the atmospheric pressure of 14.4 psi gives a total absolute pressure of 28.14 psi. - To convert psi to kPa, we multiply by 6.895. Therefore, the absolute pressure in the tank is 194 kPa (28.14 psi x 6.895).
