The figure below shows a closed tank that contains gasoline floating on water. Calculate the air pressure above the gasoline. The container is vented to the local atmosphere. What is the absolute pressure at the surface of the mercury and at the bottom of the container (kPa)? Assume the conditions of the standard atmosphere prevail for pressure. Use sg = 13.54 for the mercury
