Hi everyone,
I have an ammonia overfeed system @-30C and i am pumping it to 4 set of coolers. 6@-30,2@-20 and 4@0 .So while selecting the pump,Do i need to consider the pressure drop in all these coolers(ie,from -30 to -20 and -30 to 0)...or i need to consider only the larger pressure drop (ie -30 to 0)..please help....!
