What is Bernoulliβs Equation?
BE is a simple and easy to use relation between the pressure, velocity and elevation in a moving fluid
What is BE for steady, incompressible and inviscid flows?
π+ (ππ£^2)/2+πππ§=
πΆπππ π‘πππ‘ πππππ π π π‘ππππππππ
What is BE for two points on a streamline?
π_1+(πγπ£_1γ^2)/2+πππ§_1= π_2+(πγπ£_2γ^2)/2+πππ§_2
What can Bernoulliβs Equation be translated as?
βWork done on a fluid particle by pressure and gravity forces is equal to the change in its kinetic energyβ
Which part of BE represents Stagnation pressure?
π+ (ππ£^2)/2
What does Stagnation Pressure represent?
Stagnation pressure represents the pressure at a point where the fluid is brought to a complete stop isentropically
Dive an example of Stagnation pressure?

_____
What is the Pitot Tube with Piezometer Equation?
