Aerodynamics of a paper rocket

[this1dude]

I'm pretty new to this forum but have loved sciences if all kinds since I was young and plan to get into nuclear engineering after high school. Back on topic, I have made a rocket launcher out of pvc pipe that is powered by an air compressor. Ranging from 60-120 psi propelling my paper rocket. Since I'm often bored after school, how can I determine the air resistance and drag coefficient and well the maximum speed it reaches when propelled with 100psi. I know it'll be hard because I have to take into account gravity and air resistance and friction and the force that the 100psi hits it at but anyone who knows this stuff want to help me please?

What is the shape of your rocket? Getting a "good" drag answer here could be either fairly easy or basically impossible without computer software.

The max speed will probably occur just as it exits the launching tube. You could try filming it against a stripped background. Estimate how far it moves per frame.
