Altitude / Velocity

[bachaco]

A 5 kgm, 1 meter long, 0.1 meter diameter, projectile inside a frictinless 20 meter pipe. The projectile is pushed "vertically" at the equator by a piston with a pressure of 3000 pounds per square inch(sorry about the psi). What are the formulas to find 'drag force', 'velocity at different altitudes', and 'max. altitude attained'?
