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

The U-tube manometer is filled by several fluids as shown. Compute the pressure reading at the
manometer if hl=10 cm; h2-25 cm; h3=60 cm, and h4-20 cm. The U-tube is open to the
atmospheric pressure. Assume SG for oil 0.78 and for Hg 13.7. Water density is 1,000 kg/m³ and
air density is 1.225 kg/m³.
