QUESTION $4$

Figure $1$ shows a water distribution network that has two inflow nodes and three outflow nodes. All the pipes in the network have a diameter of $650$ mm and a length of $1000$ m $,$ and have a Hazen William coefficient of $120.$ Assume initial flows from node $A$ to pipe $AB$ and Pipe $AD$ to be equal. You are required to use the Hardy Cross method to determine:

$3\mathrm{.}1$ The discharge in the loops

$3\mathrm{.}2$ The pressure heads at point B$,$ C$,$ D and E$,$ if the pressure head at A is $120$ m $,$ and all nodes are at the same elevation.

CARRY OUT ONLY $1$ ITERATION TO CORRECT THE FLOWS.
