Chapter 7, Problem 17P

Air at 15°C and 1 atm flows over a 0.3-m-wide plate at 65°C at a velocity of 3.0 m/s. Co x = 0.3  m: mpute the following quantities at

(a) Hydrodynamic boundary layer thickness, m

(b) Local friction coefficient

(c) Average friction coefficient

(d) Total drag force due to friction, N

(e) Local convection heat transfer coefficient, W/m2 K

(f) Average convection heat transfer coefficient, W/m2 K

(g) Rate of convective heat transfer, W

Consider laminar flow over a flat plate. How does the local friction coefficient change with position?
What are the three layers within turbulent flow? In which layer is the velocity smallest and in which layer is the turbulent portion of the shear stress dominant?
Hot carbon dioxide exhaust gas at 1 atm is being cooled by flat plates. The gas at 220°C flows in parallel over the upper and lower surfaces of a 1.5-m-long flat plate at a velocity of 3 m/s. If the flat plate surface temperature is maintained at 80°C, determine (a) the local convection heat transfer coefficient at 1 m from the leading edge, (b) the average convection heat transfer coefficient over the entire plate, and (c) the total heat flux transfer to the plate.
