DragForce_Cone_r

 

 

Procedure DragForce_Cone_r returns the drag force for a cone having a spherically-blunted nose cone

 

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]

 

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_r 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:F_d,C_d,Re) 

 

{Solution:

C_d=0.136 

F_d=0.01581 [N]

Re=32020 

}
