What about air? It's going to get compressed and have to vent out the air releases. Some are about 3000' to the farthest riser and then up 60'. 6" to 4" to a vented yard wye. Friction, gravity, expansion... It can't be that easy. Really?
TD (Volume of the pipe) / (pumper truck pump rate in GPM) = time in minutes. Does anyone know where I can find information on how to calculate fill times on an exterior dry manual standpipe? It's installed along elevated roadways and bridges and will be filled by a pumper truck.
