Sea water (specific gravity = 1.03) leaks into the diesel fuel (specifc gravity = 0.81) tanks of a ship. Diesel fuel and seawater are immiscible and will not form a solution. These tanks are vented to the atmosphere. Answer the following questions when the depth of the diesel fuel in the tank is 3.74 m and the depth of the seawater is 0.56 m.
What is the gage pressure at the seawater-diesel fuel interface? in kPa
What is the gage pressure at the bottom of the tanks? in kPa
What is the absolute pressure at the bottom of the taanks assuming standard atmospheric conditions? in kPa
What equations do you use and how do you apply them to each question?
According to the hydrostatic pressure equation, DP = (S.W.) h where DP is the pressure between the top and bottom of a fluid layer and h is the height of the fluid layer. The specific weight of a fluid is the product of the fluid's specific gravity and the specific weight of fresh water, 9807 N-m-3.
