A33.8-lb aluminum bar, initially at 200 degree f, is placed in a tank together with 249 lb of liquid water, initially at 70 degree f, and allowed to achieve thermal equilibrium. the aluminum bar and water can be modeled as incompressible with specific heats 0.216 btu/lbdegree rankine and 0.998 btu/lbdegree rankine, respectively. for the aluminum bar and water as the system, determine:
(a) the final temperature, in degree f
(b) the amount of entropy produced within the tank, in btu/degree rankine.
note: ignore heat transfer between system and its surroundings

( (a) 533.7 r, (b) 0.1789 btu/r )
