What will be the total energy possessed by 1 kg of water at a point where pressure is `30" gf/mm"^(2)`, velocity is 0.5 m/s`""^(-1)` and height is 70 cm above the ground level?

Explanation

To calculate the total energy possessed by 1 kg of water at the given conditions, we need to consider three types of energy: pressure energy, gravitational potential energy, and kinetic energy. Let's go through the calculations step by step.

### Step 1: Convert Pressure to SI Units
The pressure given is \(30 \, \text{gf/mm}^2\). We need to convert this to pascals (Pa), which is the SI unit for pressure.

1. Convert grams to kilograms:
\[
30 \, \text{gf} = 30 \times 10^{-3} \, \text{kgf}
