I know there are several websites for calculating the amount of BP you need to deploy a chute (eg: https://rocketrycalculator.com/rocketry-calculator/bp-estimator/) along with factoring in shear pins and such. My question is really based on the Volume inside the parachute bay. Currently the empty volume of my bay is 10.75" x 3.9" I.D.. But when I stuff my parachute (inside a parachute bag) along with the tether lines and such, that volume goes to 0.00". Pretty much my parachute bag is now sitting on the charge cup with the BP.
So my question is do my calculations need to be adjusted for the fact that my filled tube volume is pretty much zero when everything is packed and ready for launch?
Thanks,
