A sheet of metal of 2 m ´ 2 m and 1.5 mm thickness is being tested in a wind tunnel.

A sheet of metal of 2 m ´ 2 m and 1.5 mm thickness is being tested in a wind tunnel.

a. Calculate the critical velocity, in m/s, at which the boundary layer will remain laminar.

b. For an upstream velocity of 35 m/s, what percentage of the metal sheet surface will have a laminar boundary layer.

c. For each of the previous cases (all laminar B.L and mixed laminar/turbulent B.L), calculate the drag force on the plate, in N. Use Table 9.3 to calculate the appropriate drag coefficients.

Consider a sheet of paper with a thickness of 0.1 mm and a dielectric constant of 3. Suppose we would like to make a 1 F capacitor using this sheet as a spacer between two metallic plates. Suppose we took out the paper dielectric (while keeping somehow the distance between the plates the same). 1.26: What is the charge after the paper sheet is out completely? 1.27: What is voltage across the capacitor after the paper sheet is out completely?...
