__Explanation:__

**A**perfect fluid is incompressible and frictionless and it is explained with the help of Euler's equation.- Euler's equation of motion:
- The Euler's equation for a steady flow of an
**ideal fluid**along a streamline is a relation between the velocity, pressure, and density of a moving fluid. - It is based on Newton's Second Law of Motion which states that if the external force is zero, linear momentum is conserved.
- The integration of the equation gives Bernoulli's equation in the form of energy per unit weight of the following fluid.
- It is based on the following
**assumptions**:- The fluid is
**non-viscous**(i,e., the**frictional losses are zero**) - The fluid is homogeneous and
**incompressible**(i.e., the mass density of the fluid is constant) - The flow is
**continuous, steady, and along the streamline**. - The velocity of the flow is uniform over the section.
- No energy or force (except gravity and pressure forces) is involved in the flow.

- The fluid is
