Ametal casting weighing 3.67 kg - including riser and gating system, which makes up 43% of the total volume has a melting temperature of approximately 609°c, a density of 2.74 g/cm2, a specific heat of 0.7 j/g°c in the solid state and 0.93 j/g°c in the liquid state, and heat of fusion of 483 j/g. assuming the ambient temperature in the foundry is 22°c and the specified pouring temperature is 676°c. determine the total heat required to raise the temperature of the metal for one part to the pouring temperature in terms of kj.
