5. In what circumstance, the reducer of a pump suction piping will be in bottom flat position. Explain why the reducer should be so.
Answer: This arrangement can be used if you have a pipeline completely flooded from an elevated source. The idea is to do the arrangement in such a way that top of pipe will purge the air in the way of the liquid source.
6. A P&ID shows a spec break (at Flange) between carbon steel & stainless steel specification. What additional arrangements you have to make for that dissimilar material flange joint?
Answer 2: Don't forget to use a dielectric joint.
19. A air fin cooler (2 air coolers with each having 2 inlet nozzles) needs a Typical piping arrangement. How many types of piping arrangement is possible.
Answer2: The idea is to have the same head loss (and fluid circulation) in each air cooler. For getting this, you can have a simmetrical piping arrangement from a common entering and a common leaving manifold. Other arrangement in which the common feeding manifold provides in one line the liquid for AC A by means of one tee and the rest (for AC B) in an elbow which connects to the nozzle, but the arrangement for the discharge manifold shall have an elbow in the AC A and one tee which collect the liquid for AC B. It is a little confused for my poor English.
Good questions.
