# Flow Rate Watch

1. Not sure if this is in the right category.

I have been given a flow rate of 30L collected within 36.5 seconds.
To calculate the flow rate I think it is Q= V/A is this correct?

Should you then divide the 30 / 1000 to get it in m^3 ?

0.03 / 36.5 = 0.00082

Is this correct?

The flow rate is the volume of flow per given amount of time. You have the total volume of flow and the time-frame in which it occurred. From this you can work out a flow rate in whatever unit of volume you desire (e.g. litres, which would be the easiest as no conversion would be required, or m3 if you want).

V and A refer to velocity and cross sectional area, which you do not have, but your final answer does agree with mine.
