Calculate the total energy per unit mass possessed by water at a point, where the pressure is 10 gh f//sq mm, velocity is `0.1 ms^(-1)` and height of water level from the graund is `0.20 m (g = 9.8 ms^(-2))`.

Explanation

To calculate the total energy per unit mass possessed by water at a given point, we need to consider three components: gravitational potential energy, kinetic energy, and pressure energy. The formula for total energy per unit mass (E) can be expressed as:

\[ E = \text{Potential Energy} + \text{Kinetic Energy} + \text{Pressure Energy} \]

### Step 1: Convert Pressure from `ghf/mm²` to Pascal
Given:
