For a flow through a smooth pipe, the Fanning friction factor (f) is given by f = mRe-1.2 in the turbulent flow regime, where Re is the Reynolds number and ݉ is a constant. Water flowing through a section of this pipe with a velocity 1 m/s results in a frictional pressure drop of 10 kPa.
What will be the pressure drop across this section (in kPa), when the velocity of water is 2 m/s?
