Programmed in Pure Data (Pd) and GEM, Flow Rate has been designed to calculate flow rate and create an audio-visualisation of measurements recorded at a Flow Rate Event – a participant-led field studies task to gather first-hand data from the Pent stream.
The flow rate measurement (m3) is indicated by the maximum size of the yellow cube and the pitch of sound that accompanies it. The relative values of the green and red cubes are 0.06m3 and 0.1m3 respectively and are also sounded to provide a sense of the scale. Pitch is equivalent to the cubic measurement of 0.1m per octave, beginning on the musical note C3 at 0m.
Participants are invited to continue to contribute to the work by performing the Flow Rate Event and submitting their own data.
