The Coanda Effect Calculator helps determine the pressure difference (ΔP\Delta PΔP) caused by fluid velocity and a coefficient factor. This effect is widely used in aerodynamics, fluid dynamics, and engineering applications.
Formula
The formula for the Coanda Effect pressure difference is: ΔP=V2⋅K\Delta P = V^2 \cdot KΔP=V2⋅K
Where:
- VVV = Velocity of the fluid
- KKK = Coefficient related to surface curvature and viscosity
How to Use
- Enter the velocity of the fluid in the first input box.
- Enter the coefficient related to the specific surface in the second input box.
- Click the “Calculate” button.
- The result (pressure difference) will be displayed below.
Example
Given:
- Velocity (VVV) = 5 m/s
- Coefficient (KKK) = 1.2
Calculation: ΔP=52×1.2=25×1.2=30\Delta P = 5^2 \times 1.2 = 25 \times 1.2 = 30ΔP=52×1.2=25×1.2=30
Result: The pressure difference is 30 Pa.
FAQs
1. What is the Coanda Effect?
The Coanda Effect describes how a fluid follows the contour of a surface due to pressure differences.
2. Why is the Coanda Effect important?
It is crucial in aerodynamics, fluid mechanics, and industrial applications like aircraft design and ventilation systems.
3. What units should I use in the calculator?
Use meters per second (m/s) for velocity and a dimensionless coefficient for KKK.
4. Can this calculator be used for air and water?
Yes, as long as the correct coefficient is used for the respective fluid.
5. What does a higher coefficient (KKK) mean?
A higher KKK value results in a greater pressure difference.
6. How is the Coanda Effect used in aircraft?
It helps improve lift and control airflows over wings.
7. Can this effect be observed in daily life?
Yes, examples include water flowing around a curved glass or air moving around a car windshield.
8. What happens if velocity is doubled?
Since pressure difference is proportional to velocity squared, doubling VVV increases ΔP\Delta PΔP four times.
9. Is this calculator applicable to gas flows?
Yes, as long as an appropriate coefficient is used.
10. Can the Coanda Effect influence air conditioning?
Yes, it helps in efficient air distribution in HVAC systems.

It assists in inhalers and respiratory support systems for better airflow management.
13. Is this effect related to Bernoulli’s principle?
Yes, as both involve pressure variations in moving fluids.
14. How can engineers optimize the Coanda Effect?
By designing curved surfaces to control fluid flow more effectively.
15. Why does water curve around a spoon under a faucet?
This is an example of the Coanda Effect in action.
16. Does the material of the surface affect the effect?
Yes, as different materials influence fluid adherence.
17. Can this calculator be used for wind tunnel experiments?
Yes, to estimate pressure differences in aerodynamic testing.
18. How is the Coanda Effect used in hovercrafts?
It helps direct airflow for lift and maneuverability.
19. Can we eliminate the Coanda Effect?
Not completely, but it can be minimized using design adjustments.
20. Does temperature affect the coefficient (KKK)?
