Using Microsoft Excel,

Determine flow rate in each section of welded steel pipe network shown below applying the Hardy Cross method to Loops I, II and III. All pipe diameters are $36-$inch and pipe lengths are given in the table below. Flow inputs at nodes A and D and flow outputs at nodes F and G are given in ft$^(3)//$sec$.$

$-$Solve for all pipe flow rates using Darcy$-$Weisbach head loss method.

$-$Repeat solution using Hazen$-$Williams head loss method.

$-$Calculate output pressure at nodes F$//$G if input pressure at nodes A$//$D is $100$ psi $.$
