Energy Losses In Pipes .
The Energy Losses in Pipes accessory made up of a test pipe, orientated vertically on the side of the equipment, which may be fed directly from the Hydraulics Bench supply or, alternatively, from the internal constant head tank.
These sources provide low or high flow rates that may be controlled by a valve at the discharge end of the test pipe. Head loss between two tapping points in the test pipe is measured using two manometers, a water over mercury* manometer for large pressure differentials and a pressurized water manometer for small pressure differentials.
Water discharging from the head tank is returned to the sump tank of the Hydraulics Bench.
