A vertical composite fluid column whose upper end is open to the atmosphere is composed of 5 in mercury (SG = 13.45) and 27 in. of water (p = 62 lbm/ft³ ) . Determine the absolute pressure at the base of the column in Psi. The specific gravity of mercury is relative to 62.4 Ibm/ft³ water and atmospheric pressure is 14.7 Psi. (express answer in 2 decimal places) Water hw S.G. = 1,0 PWM

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.
