Subject: Drag force generated by a diver in the water
Date: Thu, 2 Aug 2001 15:09:33 -0700

> I ran some calculations on the drag force (lbs) which would be generated by a
diver in the water as a function of the current.
> 
> These are ROUGH numbers.  I am also assuming this test subject has perfect
trim and is not moving.
> 
> The test subject was 220 lbs and 76 inches tall. I ran 4 configurations.  I
used PST 104 tanks and a 6 in EE light
> 
> Streamlined means Basic DIR setup with canister light and legs straight.
> Bent Knee means Basic DIR setup with canister light and legs bent.
