A 40-lb aluminum bar, initially at T₁ = 150°F, is placed in a tank together with 190 lb of liquid water, initially at Tw= 70°F, and allowed to achieve thermal equilibrium. The aluminum bar and water can be modeled as incompressible with specific heats ca = 0.216 Btu/lb-ºR and cw = 0.998 Btu/lb-ºR, respectively. Consider the aluminum bar and water as the system and ignore heat transfer between the system and its surroundings. Determine the final temperature T₁, in °F, and the amount of entropy produced within the tank, in Btu/ºR. Step 1 Determine the final temperature, in °F. T₁= i °F

Chapter 6 5.

A 40-lb aluminum bar, initially at T₁ = 150°F, is placed in a tank together with 190 lb of liquid water, initially at Tw = 70°F, and allowed
to achieve thermal equilibrium. The aluminum bar and water can be modeled as incompressible with specific heats c₂ = 0.216
Btu/lb-ºR and cw = 0.998 Btu/lb-ºR, respectively. Consider the aluminum bar and water as the system and ignore heat transfer
between the system and its surroundings.
Determine the final temperature T₁, in °F, and the amount of entropy produced within the tank, in Btu/ºR.
Step 1
Determine the final temperature, in °F.
Tf = i
°F
