Losses in Bends and Fittings

Losses in Bends and Fittings for Educational Laboratory.

Product Code:


Losses in Bends and Fittings

The unit is used for the investigation of pressure losses in bends, fittings and valves, as well as in constrictions and increases in size. The measured section consists of a pipe system with different fittings, a ball-cock, an increase in size and a constriction. The flow rate can be adjusted using the ball-cock. A 6 tube manometer and a spring-tube manometer are used to determine individual differential pressures. Annular measuring chambers guarantee interference-free pressure measurement. The water supply is provided by the Losses in Bends and Fittings Basic Hydraulics Bench.
