we are doing a project on propylene recovery unit.We are currently trying to make a layout of the plant.We do not know anything about the nominal velocity of the fluids.Hence we are unable to continue our work.
Thumb rule says us to consider the value as 1m/s.But we are not sure if it is applicable to all the process fliuds in our unit.
We also require to know the relative spacing between various equipments like,heat exchanger,condenser drum, condensate pump , reboiler pump etc.
