Chapter 7, Problem 7.39P

Air at atmospheric pressure and a temperature of 25°C is in parallel flow at a velocity of 5 m/s over a 1-m-long flat plate that is heated with a uniform heat flux of 1250 W/m 2 . Assume the flow is fully turbulent over the length of the plate.

  1. Calculate the plate surface temperature, T s ( L ) , and the local convection coefficient, h x ( L ) , at the trailing edge, x = L .
  2. Calculate the average temperature of the plate surface, is T ¯ s .
  3. Plot the variation of the surface temperature, T s ( x ) , and the convection coefficient, h x ( x ) , with distance on the same graph. Explain the key features of these distributions.

Consider laminar flow over a flat plate. How does the local friction coefficient change with position?
Air at 1 atm with a velocity of 4 m/s and a temperature of 50oC flows over a flat plate that is at a uniform temperature of 100oC. The plate has a length of 0.20 m and a width of 0.1 m. a) What is the average heat transfer coefficient? b) What is the heat transfer rate from plate to the air? c)What is the average friction coefficient and the drag force ? d)What is the heat transfer coefficient at x=0.15 m ?
Consider a refrigeration truck traveling at 70 mi/h at a location where the air is at 1 atm and 80°F. The refrigerated compartment of the truck can be considered to be a 9-ft-wide, 8-ft-high, and 20-ft-long rectangular box. Assuming the airflow over the entire outer surface to be turbulent and attached (no flow separation), determine the drag force acting on the top and side surfaces and the power required to overcome this drag.
