SITUATIONAL PROBLEM I: A composite wall constructed of 2.5 cm of steel (k= 60.5 W/m-K) and 5.0cm of aluminum (k=177 W/m-K) separates two liquids. The liquid on the steel side has a film coefficient of 15W/m²-K and a temperature of 400degC. The liquid on the aluminum side has a film coefficient of 30W/m²-K and a temperature of 100degC. Assuming that steady-state conditions have been reached: 1. What is the conductive heat transfer per unit area? 2. What is the total thermal resistance? 3. What is the thermal resistance from the steel-side fluid to the interface?

Water is to be heated from 10°C to 80°C as it flows through a 2-cm-internal-diameter, 13-m-long tube. The tube is equipped with an electric resistance heater, which provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so that in steady operation all the heat generated in the heater is transferred to the water in the tube. If the system is to provide hot water at a rate of 5 L/min, determine the power rating of the resistance heater. Also, estimate the inner surface temperature of the pipe at the exit.
Consider a person who is trying to keep cool on a hot summer day by turning a fan on and exposing his entire body to air flow. The air temperature is 85°F and the fan is blowing air at a velocity of 6 ft/s. If the person is doing light work and generating sensible heat at a rate of 300 Btu/h, determine the average temperature of the outer surface (skin or clothing) of the person.
