CalculatorWater flows through a horizontal duct of diameter 0.5 m with a velocity of 0.4 m/s. If the friction factor is 0.002 calculate the pressure difference between two points 24.8 m apart. Assume the density of water is 1000 kg/m3 Your answer should be in Pascals
Problem 5. The fully-developed velocity profile for laminar flow in a pipe is very different from that for turbulent
flow. For laminar flow, the velocity profile is parabolic (where is centerline velocity):
V=1-(+)²
For turbulent flow, the time averaged velocity profile can be approximated by a power-law profile:
= (1-)
Find the ratio of average velocity to centerline velocity, V/Ve, and the dimensionless radial location, 1* = r/R.
where you would need to place a Pitot tube if it is to measure the average velocity in the pipe for (a) laminar flow
and (b) turbulent flow with n = 6.0 at Rep = 20,000.
NOTE: For the integration of the turbulent profile, let r* = r/R and y* = 1 - *.
For uniform flow the driving force is balanced by the shear resistance force. State it mathematically.
