Using either the graphical or mathematical methods of calculation, determine the available volume of water at 20 psi residual pressure given the following test results:

Test hydrant: 80 psi static pressure and 40 psi residual pressure Flow hydrant: using one 2 1/2-inch outlet, with C = 0.9, pitot reading = 38 psi, and actual discharge diameter = 2.50 inches. What will be an ideal response?
