Question
Q2 (30%) Pictured below is a tank containing salt water and a layer of light lubricating oil. The
tank is pressurized such that the headspace (nitrogen) above the liquids is maintained at a pressure of
50 psig (poundsforce per square inch gauge). If the oil has a density of 750 kg/m³, and the salt water a
density of 980 kg/m³, determine the following (neglect friction):
a) What is the velocity of the salt water leaving the open emergency relief vent? Note: the valve is
also frictionless and does not affect the solution.
b) Determine the height of the fountain of salt water above the end of the vent.
