Using the given problem in the picture. Solve for: 
 
i) the final equilibrium temperature of the metal bar and the water in K*
316.19 K
416.19 K
49.76 K
294.16 K
21-30. A 1-1b bar initially at 783K is removed from an oven and quenched by immersing it in a
closed tank containing 30-lb of water initially at 294K. Each substance can be modeled as
incompressible. An appropriate constant specific heat value for the water is c = 4.187 kJ/kg-K and an
appropriate value for the metal is cm = 0.419 kJ/kg-K. Heat transfer from the tank contents can be
neglected. Determine:
