DragForce_TriangularBeam120_u
Procedure DragForce_TriangularBeam120_u returns the drag force on a isoceles triangular beam with an apex angle of 120 deg facing downstream
Inputs
Fluid$ - the name of any fluid in the EES data base. Fluid$ may be a string constant or a string variable.
T - temperature in the defined unit system [F,C,R,K]
P - pressure in the defined unit system [Pa,kPa,bar,MPa,psia,atm]
v - free stream fluid velocity in [m/s, ft/min]
H - height of the base of the triangle in [m or ft]
Outputs
F_d\L - drag force per unit length [N/m or lbf/ft]
C_d - drag coefficient {optional}
Re - Reynolds number {optional}
This procedure calls function DragCoefficient_TriangularBeam120_u to obtain the drag coefficient.
Example:
$UnitSystem SI C kPa
Fluid$='Air'
T=25 [C]
P=Po#
v=10 [m/s]
H=0.05 [m]
CALL DragForce_TriangularBeam120_u(Fluid$,T,P,v,H:F_d\L,C_d,Re)
{Solution:
C_d=1.753
F_d\L=5.19 [N/m]
Re=32020
}
