Question: =+13-6. The sensible heat-transfer coefficient for a dry surface has been determined to be 9 Bin (hr-ft -- F) [50 W/(m2-C)| at a certain Reynolds

=+13-6.

The sensible heat-transfer coefficient for a dry surface has been determined to be 9 Bin

(hr-ft -- F) [50 W/(m2-C)| at a certain Reynolds number. Estimate the total heat transfer to the surface per unit area at a location where the wall temperature is 50 F (10 C) and the state of the moist air flowing over the surface is given by 75 F (24 C) dry bulb and 65 F (18 C) wer buth Assume that the Reynolds number does not change and the Lewis number is 0.82. Assume the condensate present on the surface will increase the transfer coefficients by about 15 percent
