Also, some calculations to see just what kind of RPMs we can expect in the system. Please take a look and tell me if these look right to you. I'm dense when it comes to this stuff.
35mm Linear Length
1 frame = 18.6mm
24 frames = 446.4mm/s
RPM Calculations for Standard Reel & Split Reel Cores
diameter of reel @ base: 107.95mm
446.4 / 339.135 = 1.32 RPS
= 78.98 RPM
diameter of core: 50mm
446 / 157.08 = 2.84 RPS
= 170.4 RPM
STANDARD REEL (this represents the max, as most split reels are smaller)
outer diameter of reel @ edge = 361.95mm
outer diameter circumference = 1137mm
446 / 1137 = 0.39 rotations per second
= 23.5 RPM
Conclusion: The maximum RPM of the system will happen with a split-reel core, and is 170RPM. The minimum RPM system will occur with a full standard reel, and is 23.5RPM.
We should be able to use these figures in other calculation - IF THEY ARE CONFIRMED. Please take a look and let me know if my head is on straight.
