Problem 9.5

In many cases, we are concerned with free convectioninvolving gases that are contained within sealed enclo-sures. Consider air at 27?C and pressures of 1, 10, and100 bars. Determine the figureof meritdescribed in 9.4 for each of these three pressures. Whichair pressure will provide the most effective cooling?Hint:See 6.22.
