A thin walled tube with L = 3m and di = 5mm caries a fluid (c =
4210 J/kgK, = 280 x 10^-6
Ns/m^2, k = 0.700 W/mK, Pr = 2.1) with the mass flow rate of 0.015
kg/s and the mean inlet temperature of 90C. the tube's surface is
kept constant at 25C.
a. What is the value of the average convection heat transfer
coefficient for the problem?
b. How would you calculate the outlet temperature of the fluid?
