1. Introduction Duct system losses are the irreversible transformation of mechanical energy into heat. The two types of losses are (1) friction losses and (2) dynamic losses. Friction losses are due to fluid viscosity and result from momentum exchange between molecules (in laminar flow) or between individual particles of adjacent fluid layers moving at different velocities (in turbulent flow).
5. Method For Duct Calculation (equal friction method) 1)Draw schematic view of the duct system. 1)Make notes for air volume and mark clearly the elbow, the branch parts, the air discharge outlet. 1)Select one main ducting route (where the maximum static pressure loss occurs). 1)Select the air velocity for the main duct in accordance with the desirable air velocity.
