Ideal and real process energies. The melting point of aluminum is 645C. Its specific heat is C_p
= 810 J/kg K, and its latent heat of melting is L = 390 kJ/kg. Estimate the theoretical minimum energy needed to melt aluminum and compare this with the casting energy listed under “Ecoproperties: processing” in the data sheet for aluminum in Chapter 15. What do you deduce from the comparison?
