Parachute Size

[Blenderite]

How can you determine what size parachute your rocket needs? I am thinking that I might be using a parachute that might be too big. Any help would be appreciated.

Use google and search for rocket and water rocket simulators. You can plug in your rocket weight and size and it will tell you the descent rate for a given parachute size.
