**Streamline interpretation. The stream function can be interpreted in a number of ways. First we determine the differ- ential of ¯ψ as follows.**

## How to Find Stream Function?

Stream function is an important concept for those studying fluid mechanics and hydrology. It is a mathematical tool used to describe the behavior of a two–dimensional flow field in terms of a single scalar function.

A stream function is also referred to as a velocity potential and can be used to help predict the direction and strength of a flow.

In this article, we will look at what a stream function is, how it is derived and how it can be used to find the velocity of a flow. A stream function is a mathematical tool used to describe the behavior of a two–dimensional flow field.

It is a scalar function that is defined for a particular domain and represents the flow characteristics of a particular flow field.

Stream functions are useful for describing the behavior of a flowing fluid and can be used to analyze the flow of a two–dimensional flow field.

A stream function is also known as a velocity potential and can be used to determine the velocity of a flow. The stream function can be derived from the equations of continuity and momentum.

The equation of continuity states that the total mass of a system remains constant, while the equation of momentum states that the rate of change of momentum of a system is equal to the force applied on it. By solving these
