1. A tank when full will load 130 tonnes of salt water. Find how many tonnes of oil relatively density of 0.909 it will hold, allowing 1% of the volume of the tank for expansion.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

2. A tank with dimensions 8m x 7m x 6m is being filled with oil (RD of 0.9). How many tonnes
of oil can fill the tank if the ullage is 3m.
3. A piston weighing 12 N rests on a sample of gas in a cylinder 5.0 cm in diameter. (a) What
is the gauge pressure in the gas? (b) What is the absolute pressure in the gas?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2afedc5d-9f60-400d-81a0-2cecd7d4cc7a%2F0de60d02-b76f-47c0-abd6-c8d2033fb46b%2Foutv9zl_processed.png&w=3840&q=75)
