What does Pascal’s Principle state?
Hydraulic systems do not use pressure.
Pressure decreases with altitude.
Pressure applied to a fluid in a sealed container is transmitted equally throughout the fluid.
Dynamic pressure is the same as static pressure.
What is the formula for dynamic pressure?
Dynamic pressure = ρV
Dynamic pressure = ½ρV²
Dynamic pressure = ρV²
Dynamic pressure = ½ρV
