How To Convert Velocity To Pressure

Example 1

Input: 

  • Velocity = 15 m/s,
  • Fluid Density = 1.225 kg/m³

Calculation:

1. Use the formula:

      P=152×1.2252

2. Calculate

      152=225

3. Multiply 225 by 1.225 = 275.625

4. Divide by 2 = 137.8125

Result: P ≈ 137.81 Pa

Example 2

Input: 

  • Velocity = 20 m/s,
  • Fluid Density = 1.5 kg/m³

Calculation:

1. Use the formula:

      P=202×1.52

2. Calculate

     202=400

3. Multiply 400 by 1.5 = 600

4. Divide by 2 = 300

Result: P = 300 Pa

FAQs
