How many litres of water flow out of a pipe having an area of cross-section of

We know:

Area of cross section = 5 cm2

Rate = 30 cm/s and

Time =1 min

So, the volume of water flow is:

Volume = Volumetric rate ×">×× Time = (30 cm/s)(5 cm2)(60 s/min) = 9000 cm3 = 9 litres

Thus, 9 litres of water flows out of the pipe.
