Bernoulli Equation 1

 

In inviscid, 1dimention steady fluid flow

 

the following is 3 types of energy equation.

에너지 베르누이 방정식

 

also, mass of each Area can expressed like next expression.

 

 

The Bernoulli equation in terms of head is derived from the energy equation by dividing by mass and neglecting the Ax term.

Bernoulli’s equation in pressure form

 

 

Bernoulli Equation 2 (v = 0)

 

when flow velocity is zero, head term can expressed like next expression.

H = head, h = height
