A 1.2-lb metal bar initially at 2100oR is removed from an oven and quenched by immersing it in a closed tank containing 28 lb of water initially at 620oR. Each substance can be modeled as incompressible. An appropriate constant specific heat value for the water is cw = 1.0 Btu/lb.oR, and an approximate value for the metal is cm = 0.1 Btu/lb.oR. Heat transfer from the tank contents can be neglected. Determine:
a) the final equilibrium temperature of the metal bar and the water, in oR
b) the amount of entropy produced, in Btu/oR
