Water flow in pipes

Struggling

Would just like to know if it is possible to work out the velocity and diameter of pipe?

1. The problem statement, all variables and given/known data
I have a 140m dead end pipe with 200kpa of pressure applied at the entrance. there are 21 exit points and the simultaneous demand of flow rate is 2.72 l/s


2. Relevant equations
Bernoulli's?


3. The attempt at a solution
was a complete failure
