Problem set #1

A 0.2 ft3 aluminum bar with density of 169 lb/ft3, initially at 200°F, is placed in an open tank together with 4 ft3 of liquid water, initially at 70°F with specific volume = 0.01605 ft3/lb. For the water and the bar as the system, determine the final equilibrium temperature, in °F, ignoring heat transfer between the tank and its surroundings. ................
