Ductwork sizing, calculation and design for efficiency
Now we calculate the dynamic loss for the straight path through the tee, using the formula co multiplied by rho multiplied by v squared divided by 2. If we drop our values in we get the answer of 0.934 pascals so add that to the table. Then we can calculate the dynamic loss for the air which turns into the bend.
