Air flows at 27 C over a bluff body, 12 cm wide, held at 77 C.The measured heat flux is 646 W/m^2 when the air moves at 2 m/s and3590 W/m^2 at 18 m/s. In a second test, everything else is thesame, but now 17 C water at 0.4 m/s is used, giving qw = 131000W/m^2. Assuming a correlation in the from NuL = CRe^aPr^b. Estimatethe constants C, a, and b.
