: A manometer is being used to measure the pressure in a pressurized air tank. The air tank is partially filled to a depth of (h1) with a fluid of specific gravity (S1). The specific gravity of the manometric fluid is (S2), and the elevation difference between the two tubes of the manometer is (h2). Given the values of h1[cm],h2[cm],S1[], and S2[], calculate the gage pressure of air inside the tank in [Pa]
