[PSUBS-MAILIST] air compensation

[Jon Wallace via Personal_Submersibles]

 Can someone check my math?  I’m trying to get a better handle on air compensated consumption.  At 37oz volume, each MK101 would consume .03864 cu ft of air at sea level and .34776 cu ft of air at 300 foot depth.  Given four motors that would total 1.4 cu ft of air consumption per 300 foot dive and allow for approximately 57 dives with an 80 cu ft tank dedicated for the motors.  
Cliff, does this sound accurate or do you feel you were consuming more air than these figures would indicate?

 Cliff, I am wondering if you can reduce the volume of air inside the motor to reduce air consumption?  Maybe some form fitted plastic inserts between the magnets etc. I have just discovered a nice feature while connecting my rear thrusters to the air compensation  system this morning.  You can pressure test for leaks with your soapy water sprayer. Hank_______________________________________________
