DragForce_Cone
Procedure DragForce_Cone returns the drag force on a cone with an vertex angleof alpha facing upsteam
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]
D - diameter of the base of the cone in [m or ft]
alpha - vertex angle
Outputs
F_d - drag force per unit length [N or lbf]
C_d - drag coefficient {optional}
Re - Reynolds number {optional}
This procedure calls function DragCoefficient_Cone(linkID=1190} to obtain the drag coefficient.
Example:
$UnitSystem SI C kPa
Fluid$='Air'
T=25 [C]
P=Po#
v=10 [m/s]
D=0.05 [m]
CALL DragForce_Cone_r(Fluid$,T,P,v,D,alpha:F_d,C_d)
{Solution:
C_d=0.136
F_d=0.01581 [N]
