Consider a steam pipe of length l = 15 ft, inner radius r1=2 in, outer radius r2=2.4 in, and thermal conductivity k = 7.2 btu/hr-ft-of. steam is flowing through the pipe at an average temperature of 250of, and the average convective heat transfer coefficient on the inner surface is given to be h = 1.5 btu/hr-ft2-of. if the average temperature on the outer surfaces of the pipe is t2=160of, evaluate the rate of heat loss from the steam through the pipe.

In a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. what should be the radius of curvature of the cornea such that the image of an object 40.0 cm from the cornea’s vertex is focused on the retina?
