In the limit as the fluid wedge shrinks to a point, Δz→0 and Equ. Since olden times fluid has mostly been used mechanically for generating motive power, but in recent times it has been used for power transmission or automatic power control. At any point in a fluid at rest, the pressure is the same in all direction. If certain processes require more or less force or a different fluid, pressure transformers and fluid separators are a quick and cost-efficient solution. Atmospheric pressure is another example of pressure due to the weight of a fluid, in this case due to the weight of air above a given height. Introduction o Fluid static is the study of pressures throughout a fluid at rest. The final topic of the lecture is Bernoulli’s Equation. Atmospheric pressure therefore pushes down on each side equally so its effect cancels. Flow measurement B. Fluid properties C. Fluid statics D. Energy, impulse, and momentum equations E. Pipe and other internal flow 7% of FE Morning Session Up to 15% of FE Afternoon Session Afternoon (Depends on Discipline) A. Bernoulli equation and mechanical energy balance B.
