Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

Compute the pressure difference between m and n, in pounds per square inch, when:

a) Fluid A is brine (sp gr 1.15), the gage fluid is oil (sp gr 0.92), and z = 49.69 in.
b) Fluid A is water, the gage fluid is air, and z = 19.69 in.
