Question

Explain how each of the following terms relate to the Bernoulli equation: a. static pressure b. dynamic pressure .stagnation pressure d. total pressure

Answer 1

Step-by-step explanation:

We know that Bernoulli equation is the energy conservation equation.This equation given as

`(P)/(\rho g)+ (V^2)/(2g)+Z=C`

Where

P = Pressure

V= Velocity

Z= Elevation from reference

g= Acceleration due to gravity

ρ=Density

The above can be also written as

`P+ (\rho V^2)/(2)+\rho gZ=C`

ρ g Z = Static pressure

`(\rho V^2)/(2)=Dynamic\ pressure`

Stagnation pressure = Static pressure + Dynamic pressure

`Stagnation\ pressure=(\rho V^2)/(2)+\rho gZ`

`The\ total\ pressure = (P)/(\rho g)+ (V^2)/(2g)+Z`
