DuctExtractTee_CL
Returns the pressure drop associated with an extract duct with an equal area tee. The ducts have circular cross-section. The pressure drop should be applied to the flow in branch 1. The function calls the K_extract_tee function from the minor loss library.
DELTAP = DuctExtractTee_CL(F$, m_dot_3, m_dot_1, T, P, A_3)
Inputs:
F$: 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 main duct downstream of 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)
Output:
DELTAP: pressure drop (bar, atm, Pa kPa, or MPa)
