Flow Rate

Audio-visualisation of data collected from a Flow Rate Event – a participant-led field study task to gather data and measure the flow rate of the Pent stream – on 3rd October 2020. Programmed in Pure Data (Pd) and Gem.

The calculated flow rate (m3) is indicated by the maximum size of the yellow cube and the pitch of the 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 scale. Pitch is equivalent to the cubic measurement of 0.1m per octave, beginning on the musical note C3 at 0m.
