We then need to compute the dynamic loss because of the bend modifying the path of stream. For that we make use of the method Co multiplied by rho multiplied by v squared divided by 2 where co is our coefficient, rho will be the density of the air and v would be the velocity.

As an alternative to working with fuel such as oil or purely natural fuel to deliver warmth, ducted and ductless heat pumps extract warmth from the surface air and transfer it indoors to supply heat.
