Express the Bernoulli equation in three different ways using (a)energies, (b)pressures, and (c) heads.
Step 1 of 4<
p>We have to express the Bernoulli’s theorem in terms of energy, pressure and head. Step 2 of 4<
p>To express the Bernoulli’s theorem in terms of energy use the conservation of energy.
Consider a small volume of fluid with volume , of length and area of cross section . Also consider the velocity of the fluid is , density is , pressure is , and the height is
Then the kinetic energy is
The potential energy is
And the work done due to the pressure to flow from one side of the volume to the other side fo the volume is
Hence the total energy is
constant (from the conservation of energy)
Now divide the equation with respect to the , we get
This is the Bernoulli's equation in energy terms.
