How do HP, Torque, and backpressure get along?

[Rattman]

Bends can be equated to a lengh of pipe as far as head loss, but they do not contain the same amount of fluid mass as a length of pipe. So bends = unrecoverable loss. Best Idea is to Limit bends, limit change in pipe size, also an unrecoveralbe loss. The best flow will come form consistency.
