Fluent Profile Mass loss problem

I am simulating a set of 12 connected pipes, because high mesh volume, I am simulating every pipe by itself, and I write the outlet velocity for each pipe to be used as inlet condition for the next pipe.

the problem I have, for example if the velocity at the outlet of pipe 1 is 4 m/s which gives me mass flow of 50 kg/s, when I read that to the inlet of next pipe, it becomes,3.8 m/s which essentially decreases my mass flow rate.

Can anybody help?
