DuctSupplyBranchCon90_CL
Returns the pressure drop associated with a supply duct with a branch. The branch is at 90 degrees and has a conical inlet and the ducts have circular cross-section. The pressure drop should be applied to the flow in the branch. The function calls the K_supply_branch_conical_90 function from the minor loss library.
DELTAP = DuctSupplyBranchCon90_CL(F$, m_dot_3, m_dot_1, T, P, A_3, A_1)
Inputs:
F$: fluid string identifier
m_dot_3: mass flow rate in main duct upstream of branch (kg/s, lbm/hr)
m_dot_1: mass flow rate in branch (kg/s, lbm/hr)
T: inlet temperature (K, C, F, or R)
P: inlet pressure (bar, atm, Pa, kPa, or MPa)
A_3: upstream duct area (m^2 or ft^2)
A_1: branch duct area (m^2 or ft^2)
Output:
DELTAP: pressure drop (bar, atm, Pa kPa, or MPa)
