DuctExtractBranch90B_CL
Returns the pressure drop associated with an extract duct with a branch. The branch is at 90 degrees and the ducts have circular cross-section. The pressure drop should be applied to the flow from the branch. The function uses the information from the Lindab website.
DELTAP = DuctExtractBranch90B_CL(F$, v_3, v_1, T, P)
Inputs:
F$: fluid string identifier
v_3: velocity in main duct upstream of branch (m/s, ft/s)
v_1: velocity in branch (m/s, ft/s)
T: inlet temperature (K, C, F, or R)
P: inlet pressure (bar, atm, Pa, kPa, or MPa)
Output:
DELTAP: pressure drop (bar, atm, Pa kPa, or MPa)

$UnitSystem SI Mass kJ C Pa
$VarInfo DP Units='Pa'
F$ = 'Air'
T = 20 [C]
P = 100000 [Pa]
v_3 = 8 [m/s]
v_1 = 8 [m/s]
DP = DuctExtractBranch90B_CL(F$, v_3, v_1, T, P)
{Solution:
DP = 38.49 [Pa]}
