# Fluid Mechanics: Parts of the Bernoulli's Equation

The Bernoulli's equation is a combination of dynamic and static pressure. The dynamic pressure is represented by equation 1.

(1)

P_{D} = Dynamic Pressure

ρ = density

v = velocity

Combining the initial gage pressure and dynamic pressure will result in the stagnation pressure. Refer to equation 2.

(2)

P_{stag} = Stagnation Pressure

P_{1} = Initial Gage Pressure

Finally, the static pressure is represented by equation 3. Notice it's the same equation used to calculate hydrostatic pressure, which means it represents the pressure head.

(3)

P_{S} = Static Pressure

γ = Specific Weight

z_{1} = Fluid Head
