Question
A tank containing helium has a manometer attached, as shown in the figure. The local atmospheric
pressure, Po, is 100 kPa and the gravitational acceleration is 9.81 m/s. The heights of each fluid
in the manometer are hi = 330 mm, h2 = 460 mm and h3 = 500 mm. Assume the densities of the
water (pw), light oil (poi), and mercury (pH2) in the system are equivalent to those at standard
atmospheric conditions. Determine the pressure of the helium in the tank, PHe, in kPa.
