A thin plate 0.7 m long and 1.5 m wide is submerged and held stationary in a stream of 10°C water that has a velocity of 1.5 m/s.
a. What is the critical distance along the plate when turbulence begins?
b. What is the thickness of the boundary layer at this distance?
c. What is the shear stress on the plate at this distance?
d. What is the velocity in the boundary layer at a point 0.4 m down the plate (in the x direction) and 0.001 m above the surface (in the y direction)?
