Pressure drop in pipe due to bends and/or pressure reducing valves ?

I am currently doing my final year project and have a few queries. I would be really grateful if someone could answer the following questions for me as soon as possible.
• The requirement is to drop the pressure from 140-150 bars at the inlet of a pipe to 2 bars at the outlet of the pipe.
• The pressure of 2 bars is to be maintained at the outlet of pipe.
• The pipe length is 1-2 metres long.
• Pipe is made of copper or a copper alloy.
• The pressurized gas used is Nitrogen.
• The pipe diameter is not fixed yet and can be varied (but is to be kept as small as possible).

Please answer the following questions for me:
• Can the pressure drop be achieved using only bends in the pipe?
• Would using a pressure reducing valve be a better option?
• Or should both of the above options be considered?
• For any option chosen please let me know the calculations involved. The unknown variables can be assumed over a standard range.

Thanking you,

Anshuman

If you have enough money in the project, a "back pressure regulator" is your best choice.

Fisher and Jordan make industrial strength regulators. You may be able to find something cheaper if you need.
