DragForce_Ogive_t
Procedure DragForce_Ogive_t returns the drag force for an ogive having a truncated nose
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 - maximum diameter of the ogive in [m or ft]
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_Ogive_t 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_Ogive_t(Fluid$,T,P,v,D:F_d,C_d,Re)
{Solution:
C_d=0.152
F_d=0.01767 [N]
Re=32020
