What form does Bernoulli's equation take if we use the information in the problem statement that P1=P2?
In that case, V^2/2 + g y = constant
y is elevation and V is fluid velocity.
g is the acceleration of gravity
thank you
To determine the form of Bernoulli's equation when the problem statement specifies that P1 = P2, we first need to understand the general equation. Bernoulli's equation relates the pressure, velocity, and height of a fluid in a streamline.
The general form of Bernoulli's equation is:
P1 + 0.5ρv1^2 + ρgh1 = P2 + 0.5ρv2^2 + ρgh2
Where:
P1 and P2 are the pressures at points 1 and 2 along the streamline,
ρ is the density of the fluid,
v1 and v2 are the velocities of the fluid at points 1 and 2,
g is the acceleration due to gravity, and
h1 and h2 are the heights of the fluid at points 1 and 2.
If the problem statement specifies that P1 = P2, we can simplify Bernoulli's equation by removing the pressure terms. This is because the pressure difference is zero in that case.
Hence, the simplified form of Bernoulli's equation, when P1 = P2, becomes:
0.5ρv1^2 + ρgh1 = 0.5ρv2^2 + ρgh2
This simplified equation still relates the velocity and height of the fluid at different points along the streamline, but without considering pressure.
