Problem 1.3 Mercury is used as the working fluid for measuring the pressure of water by a U-shaped manometer. The water pressure at one entrance of the manometer, p₁, is 300 k Pa, and pressure at the other entrance, p2, is 230 k Pa. Calculate the mercury column height, H. The densities of the mercury and water are 13,600 kg/m³ and 1,000 kg/m³, respectively.
