We then really need to determine the dynamic reduction a result of the bend changing the path of circulation. For that we make use of the system Co multiplied by rho multiplied by v squared divided by two where co is our coefficient, rho will be the density in the air and v could be the velocity.
We are able to calculate just how much strain fall Every damper wants to provide merely by subtracting the lack of the run from the index operate.
