turbulence, as given by Eq. (8.54). All
pipes are cast iron, and are at the same
elevation. For initial flows, assume only
values of 30, 15, and 0 L/s (the zeros in dg
and fh). If the pressure head at a is 40 m,
find the pressure head at d (which might
represent a fire demand, for example)
neglecting velocity heads.
