Throw some dimensional analysis into the equations that you were using, and you'll find with your method of equating torque (fxl) with "f", you are out by an "l" component...therefore the formula as you applied it is incorrect...formula is, but can't use any number or colour that you like, or it becomes nonsense.
Imagine a bare crank resting in its bearings. Attach a lever to the end of the crank. Push down on the lever. The crank will rotate. The force it took to rotate the crank is torque. Load as used for the flow calculations is the weight the crank places against the bearings. Torque applied to the crank in low friction bearings has virtually no effect on load.
Turtlevette, does that help you see the difference?
