Flow rate ( Q) = V * A
V- velocity A - cross sectional area

Our velocity is given as 20cm/sec Convert this to cm/min 20cm/sec * 60seconds = 1200cm/min

Plugging in this value into our equation for flow rate we get 1200cm/min * 2 square cm = 2400 cubic cm /min

Note : 1000 cubic cm = 1 L and therefore we can convert our answer to L/min which are the required units by dividing by 1000

= 2.4 L/min
