    1. The problem statement, all variables and given/known data

    how are litres related to meters???? (with respect to flow rates.

    so for eg, if something goes 20litres per minute, then how do you convert that to the fluids velocity??

    (so i think im having probs cuz i cant seem to get the difference between a litre and a meter, (are meters cubed litres??)

    2. Relevant equations

    3. The attempt at a solution

    If its water then a cubed meter is 1000 kg. A metric ton. A liter of water is 1000th of that. One kg. If its any other fluid then all bets are off.

    You need to know the cross sectional area.
    Volume = length * area
    So flow rate (volume/s) = area * speed (length/s)
