  • Calculate are of a pipe if, flow rate is 20 L/min and flow velocity is 5 cm/s. -Uttamkumar Jagtap (08/19/17)
  • Given: Flow Rate = 20 litre/min.
    Flow Velocity = 5 cm/s
    Formula: Flow Rate = Velocity x Area
    Solution: 
    Flow rate = 20 litre/min
    = 20,0000 cm3/60s
    = 333.33 cm3/s
    Flow Rate = Velocity x Area
    333.33cm3/s = 5cm/s x Area
    Area = 333.33cm3/s / 5 cm/s
    = 66.66 cm2

    Are of a pipe is 66.66 cm2
