Answer #1

The above calculations shows the generalised procedure to calculate the Reynolds number.

Re = 8766

given that the velocity profile is parabolic and parabolic profile will only obtain in Laminar flow

and for Laminar flow through pipe the Reynolds number should be below 2000, hence there might be some mistake with given data, please verify the given data and perform the above mentioned steps.

Water flows through a constricting pipe. At the inlet, the pressure is 100,000 Pa, the diameter is 1.6 m and the water flows at 1 m/s. The centerline of the outlet of the pipe is the same as the centerline of the inlet of the pipe. Solve for the PRESSURE and VELOCITY of the water exiting the pipe if the diameter is 0.8 m. I know Bernoulli's equation, it's the solving for two unknowns that has me lost.
