Straightening the pipe will surely increase the pressure, but putting a 2 inch pipe will increase the pressure substantially more. The effect of 90 degree bend is linear on pressure drop whereas effect of diameter is to the fourth power on pressure, i.e., if the diameter is doubled, the pressure is affected by factor of 16. This is given in many fluid mechanics textbooks. They can refer to Fluid Mechanics by Frank White, McGraw-Hill Pub. or Introduction to Food Engineering by Singh and Heldman, 2nd Ed., Academic Press. -MVK
