## flow rate

 Quote by JimiJams so suppose there's a single pipe that forks into two branches, how do you calculate the flow rate of each branch? Would it be divided equally, or would it depend on which branch has the smallest section within its branch, or which branch begins with the largest diameter?
This problem is fully analogous to solving an electrical circuit. See https://en.wikipedia.org/wiki/Kirchh...s_circuit_laws

The standard way to do this is to assign a resistance to each pipe section. A fork is a point where multiple pipe sections meet. Then you calculate the currents in each pipe section and "potentials" (essentially water pressure) at each node (fork point).

Please, please do not introduce this analogy. It does not work for pipe networks. That is the reason Professor Hardy Cross introduced his famous method.
