Two volumes of liquid water at different temperatures are in well-stirred adjacent chambers as shown in Figure P3.1 and the subsequent table. The initial water temperatures in Chambers 1 and 2 are 20 and 70 ◦C, respectively. There is no mass flow into, out of, or

between the tanks, and the two-tank system is completely insulated from the surroundings. The tanks can exchange heat through the glass wall separating the two chambers, which has a thickness of 2.4 cm and a total surface area of 0.25 m². The following data were collected

a. Determine the system equilibrium temperature.

b. Write the basic energy balance equations for this system.

c. Estimate the heat transfer coefficient of the system.
