Note that L/min =
==> speed of water = (volume speed)/(cross-sectional area of pipe) = , where we used
==> speed of water = = 0.003 kph

A cylinder pipe has inner diameter of 7cm and water flows through it at the rate of 192.5 litres per minute. Find the speed of water in km/hour
----------
192.5 liter/min = 192500 cm^3/minute
----
Area = pi*r^2 = 12.25pi cm^2
---------
192500/(12.25*pi) = 770000/(49pi) = 110000/(7pi) cm/minute
= 110/(7pi) km/minute
= 6600/(7pi) km/hr
=~ 300.12 km/hr
