F1-18 Energy Losses in Pipes

 

F1-18 Energy Losses in Pipes

The unit consists of a vertical test pipe on the side of the equipment which can be fed directly from the hydraulics bench supply or, alternatively, from the integral constant head tank above.
These in turn provide high or low flow rates which may be controlled by a valve at the discharge end of the test pipe. Manometers are used to measure the head loss. For large pressure differentials we would recommend the Armfield H12-8 Digital Pressure meter, although a water-over-mercury manometer is also built into the unit. In addition, a pressurised water manometer for small pressure differentials is also fitted to the unit.

Description

The unit consists of a vertical test pipe on the side of the equipment, which can be fed directly from the Hydraulics Bench supply or, alternatively, from the integral constant head tank above.

These in turn provide high or low flow rates which may be controlled by a valve at the discharge end of the test pipe. Manometers are used to measure the head loss. For large pressure differentials we would recommend the Armfield H12-8 Digital Pressure meter. In addition, a pressurised water manometer for small pressure differentials is also fitted to the unit.

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 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 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.

Mercury is not supplied.

The H12-8 Digital Pressure Meter is available as an alternative to mercury manometers – for more information view online: www.armfield.co.uk/h12-8
