Water (pw= 997 kg/m³, Cp,w = 4179 J/kg·K, µw = 855×106 N•s/m², kw = 0.613 W/m•K, and Pr, = 5.83) enters a thin-walled (negligible thickness) tube of 10-mm diameter and 2-m length with mass flow rate m, =0.2 kg/s and inlet mean temperature Tm,i = 47°C. The tube is heated by passing air at T = 100°C and velocity V = 10 m/s in cross flow over the tube. The properties of the cross flowing air are evaluated as vair= 20.92×10-6 m2/s, kair=0.03 W/m•K, Prair=0.7. Determine the exit temperature of the water leaving the tube and the total heat loss from the water as it passes through the tube. Tm,0 = 46.62°C

In a quiescent hot summer day, you are walking under the sunlight. Suddenly, you remember heat transfer lecture that you have successfully failed. Explain the mechanisms of heat transfer that are falling on you? Which one is dominant and why? b) Hot air at 50 C does not cause a lethal burn on our skin, but water with the same temperature is dangerous and it can burn our skin. Explain the reason? Any SAME answer from the internet sources or your friends will give you ZERO (0) point.

..P15 A horizontal cylinder 10 cm in diameter contains helium gas at room temperature and atmospheric pressure. A piston keeps the gas inside a region of the cylinder 20 cm long. (a) If you quickly pull the piston outward a distance of 12 cm, what is the approximate temperature of the helium immediately afterward? What approximations did you make? (b) How much work did you do, including sign? (Note that you need to consider the outside air as well as the inside helium in calculating the amount of work you do.) (c) Immediately after the pull, what force must you exert on the piston to hold it in position (with the helium enclosed in a volume that is 20 + 12 = 32 cm long)? (d) You wait while the helium slowly returns to room temperature, maintaining the piston at its current location. After this wait, what force must you exert to hold the piston in position? (e) Next, you very slowly allow the piston to move back into the cylinder, stopping when the region of helium gas is 25 cm long.…
