Question
You are asked to calculate the pressure drop in a
straight pipe. Air of density 1.225 kg/m³ is flowing
through the pipe. The diameter of the pipe is 25
mm. The velocity of the flow is 1 m/s. The viscosity
of air is given as 1.85 x 10-5 Pas.
From this information the Reynolds number was
calculated to be 1655.
Determine the Head drop if the pipe is 100 m in
length.
Hint: For laminar flow the fanning friction factor can
be calculated as 16/Re
