DuctDamperParallel_Cl

 

 

Returns the pressure drop associated with a damper that has parallel vanes given the fluid, its flow rate and state, the upstream area, and the vane angle.  This function calls the K_damper_parallel function from the minor loss library.

 

DELTAP = DuctDamperParallel_CL(F$, m_dot, T, P, A, theta)

 

Inputs:

F$:  fluid string identifier

m_dot:  mass flow rate (kg/s, lbm/hr)

T:  inlet temperature (K, C, F, or R)

P:  inlet pressure (bar, atm, Pa, kPa, or MPa)

A:  upstream duct area (m^2 or ft^2)

theta:  vane angle (radian or degree)

 

Output:

DELTAP:  pressure drop (bar, atm, Pa kPa, or MPa)

 

Example: 

$UnitSystem SI Mass J K Pa Degree

$Load Component Library

$VarInfo DP units=Pa

 

m_dot = 0.5 [kg/s]

T = 300 [K]

P = 100e3 [Pa]

A = 0.05 [m^2]

F$ = 'Air'

theta = 50 [degree]

DP = DuctDamperParallel_CL(F$, m_dot, T, P, A, theta)

 

{Solution:

DP = 524.5 [Pa]}
