insulated vessel

6.67   An insulated vessel is divided into two equal-sized compartments connected by a valve. Initially, one compart- ment contains steam at 50 lbf/in.2 and 7008F, and the other is evacuated. The valve is opened and the steam is allowed to fill the entire volume. Determine

(a)    the final temperature, in 8F.

(b)    the amount of entropy produced, in Btu/lb ? 8R.

 

where k is the thermal conductivity of the copper  rod.

(a) For the rod as the system, obtain an expression for the time rate of entropy production in terms of A, L, TH, TC, and k.

 

#
 

(b) If TH 5 3278C, TC 5 778C, k 5 0.4 kW/m ? K, A 5 0.1 m2,

plot the heat transfer rate QH, in kW, and the time rate of entropy production, in kW/K, each versus L  ranging   from

0.01  to 1.0 m. Discuss.
