Question

Which of the following statements about the Bernoulli equation wrong?

a. The Bernoulli equation assumes that kinetics energy remains conserved

b. The Bernoulli equation assumes incompressible flow

c. The Bernoulli equation assumes that viscosity effects are negligible

d. The Bernoulli equation assumes that the volume flow rate is constant everywhere

Answer 1

Answer : the following statements about the Bernoulli equation wrong :

• (a) The Bernoulli equation assumes that kinetics energy remains conserved.

Because, According to Bernoulli equation which states that in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline. Which implies that the sum of kinetic energy, potential energy and internal energy remains constant - Not only kinetic energy but sum of kinetic energy, potential energy and internal energy remains constant.
