Tom pose la question :
My question is this I know the equations for the final answer but the book skips how to get to one section of the equation. Q=(a)(v)
A= The cross-sectional area of the conduit in square feet (ft2). So if you have a 5 inch hose how do they get A=0.136 ft2 ? And I know the velocity already v= velocity in ft per second.
