1 litre=1dm3=1/1000 m3
1 minute=1/60 heure
475l/mn=475*(1/1000)/(1/60)
=475*60/1000
=475*6/100
=28,5 m3/h

En fait il faut utiliser un calcule simple comme 1min*60=1h
475l*60=28500l donc 28500l/1h ce qui fait 28.5m3/1h vu que 1l=1dm3 ce qui fait que 1dm3=0.001m3.Donc en fait le temps est proportionnel au nombres de litres.

475litres = 0,475M3
1H = 60mns
