hi,
Can someone please help me with this question:
determine the pressure drop along a 0.1m section of pipe for turbulent flow.
density - 1.23kg/m^3
viscosity - 1.79 x 10^-5N.s/m^2
diameter - 4.0mm
Velocity - 50m/s
roughness - 0.0015mm

If not you have to consider the elevation change in the calculation and the pipe is horizontal I recommend this page Fluid Pressure Drop along a pipe of uniform diameter

If the pipe is not horizontal you have to consider the elevation change.

Caution Reynolds number and friction coefficients are dimensionless numbers---make sure all dimensions cancel.
