A 50 lb iron casting, initially at 700 degree Fahrenheit, is quenched in a tank filled with 2121 lb of oil, initially at 80 degrees farenheit. The iron casting and oil can be modeled as incompressible with specific heats 0.10 Btu/lb * degree Rankin, and 0.45 Btu/lb * degree Rankine, respectively. For the iron casting and the oil as a system determineA) the final equilibrium temperature ( in degree Farenheit)B) the amount of entropy produced within, Btu/degree Rankin. (Ignore heat transfer between the system and its surroundings)
