A fluid with a constant density of 961 kg/m3 and a constant viscosity of 1.419x10-3 Kg/m-s is flowing over a flat plate at a stream free velocity of 0.87 m/s. If the plate has a length of 2 m, answer the following: 1. What is Reynolds number at a point that is (1/4)L down the entrance? 2.Is the flow laminar or turbulent? 3.Calculate the thickness of the boundary layer in mm at (1/4)L down the entrance.

Question
A fluid with a constant density of 961 kg/m3 and a
constant viscosity of 1.419x10-3 Kg/m-s is flowing over
a flat plate at a stream free velocity of 0.87 m/s. If the
plate has a length of 2 m, answer the following:
1. What is Reynolds number at a point that is (1/4)L
down the entrance? 2.Is the flow laminar or
turbulent? 3.Calculate the thickness of the boundary
layer in mm at (1/4)L down the entrance.
