Basic Aerodynamic equations

Hi, 

I have some basic aerodynamic equation questions.  If the equations
are too complex and require all sorts of other variables such as air
density, altitude, temperature, just provide a simpler form of the
equation (in effect the first order approximation).

Here are the basic variables I am using

F – thrust in units of lb
d – air flow in units of cubic feet per second
v – velocity of air pushed out at the back end of the engine in feet
per second
a – surface area in ft squared
x – angle of attack in degrees


#1  AIR FLOW - THRUST
For a propeller or fan based engines, what is the equation for
computing thrust based upon cubic feet of air moved per unit of time? 
F = f (d, v)


#2 – PRESSURE – AREA
What's the equation for computing pressure or force on a unit of area
if air is moving a specific velocity?  Assume the area is
perpendicular to the airflow (angle of attack = 90 deg).  F = f (a,
v).

#3 - #2 for ANGLE OF ATTACK
F = f(a, v, x)?

Thanks.
