How Do Liters Translate to Meters in Flow Rates?

AI Thread Summary
Liters and meters relate to flow rates through the concept of volume and velocity. One liter is equivalent to one cubic decimeter, and there are 1,000 liters in a cubic meter. To convert flow rates from liters per minute to fluid velocity, the cross-sectional area of the flow must be known. The relationship can be expressed as flow rate equals area multiplied by velocity. Understanding these conversions is essential for calculating fluid dynamics accurately.

Homework Statement



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 I am having probs because i can't seem to get the difference between a litre and a meter, (are meters cubed litres??)
thanks.

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)

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
