State Bernoulli’s Principle. A man standing while on a railway platform, feels a push towards the train as train is passing the man with high speed. Explain the above event using Bernoulli’s Principle.

Explanation

### Step-by-Step Solution:

1. **State Bernoulli’s Principle**:
Bernoulli’s Principle states that for an incompressible, non-viscous fluid flowing in a streamline motion, the sum of the pressure energy, kinetic energy, and potential energy per unit volume remains constant along a streamline. Mathematically, it can be expressed as:
\[ P + \frac{1}{2} \rho v^2 + \rho gh = \text{constant} \]
where \( P \) is the pressure, \( \rho \) is the fluid density, \( v \) is the fluid velocity, and \( h \) is the height above a reference level.
