Description

The Energy Losses in Pipes accessory consists 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 integral constant head tank.

These sources provide high or low flow rates which can 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, digital hand held manometer for large pressure differentials and a pressurised water manometer for small pressure differentials.

Excess water discharging from the constant head tank is returned to the sump tank of the hydraulics bench.

Adjustable feet permit levelling.

Experimental Content

• To investigate the head loss due to friction in the flow of water through a pipe and to determine the associated friction factor over a range of flow rates in laminar flow
• To investigate the head loss due to friction in the flow of water through a pipe and to determine the associated friction factor over a range of flow rates in turbulent flow
• Determining the critical Reynolds number
