Wives Tale about a -8 hose being .500 id

Aeroquip hoses are not as ASSUMED for inside diameter and area.
A -8 hose is not a .500" inside diameter with a .2 sq in of area. It is about 25% LESS.


Actual--------Assumed---------Actual-------Assumed--------Percentage
Diameter-----Diameter---------Area-----------Area------------Of Error

0.22------------0.25-------------0.04-----------0.05-------------0.23
0.34------------0.38-------------0.09-----------0.11-------------0.18
0.44------------0.5--------------0.15-----------0.2---------------0.23
0.56------------0.63-------------0.25-----------0.31--------------0.2
0.69------------0.75-------------0.37-----------0.44--------------0.15
0.88-------------1.0-------------0.61-----------0.79--------------0.23

If you want at least a .2 sq inches of area you need to step up to -10 hose.
.8 hose has .15 sq in of area. Roughly a 25% smaller area than assumed
