We then ought to compute the dynamic loss a result of the bend transforming the path of flow. For that we use the formulation Co multiplied by rho multiplied by v squared divided by 2 the place co is our coefficient, rho may be the density in the air and v is definitely the velocity.
This Do it yourself process generally cleans only about ten ft into Each individual vent, that's a fraction of the complete duct system.
