Q:- An 8-cm-diameter piston compresses manometer oil into an inclined tube, as shown in Fig. When a weight W is added to the top of the piston, the oil rises an additional distance of 10 cm up the tube, as shown. How large is the weight, in N?

Q: If a closed tank contains compressed air and oil (SGoit = 0.90), with a U-tube manometer using…

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.
