Losses in Piping Systems — MOE Lab Tender Details

Losses in Piping Systems

Shows pressure losses in several small-bore pipe circuit components, typical of those found in central heating installations

Experiments
A comprehensive range of investigations into losses in a variety of pipes and pipe system components, including:
Straight pipe loss
Sudden expansión
Sudden contraction
Bends with different radius
Valves
Elbows
Flow in a roughened pipe – needs the optional Roughened Pipe

Pressure loss across valves measured by pressure gauge
Pressure across all other component to be measured by 8 piezometer tubes
Distance L between pressure tappings = 0.914 m.
Hand pump to be supplied to adjust the datum position of the manometers.
