Steel is forged at temperature of 1316C A 1.8 kg mass of steel is quenched in a bath of 2.5kg of water raising the water temperature from 25C to 100C.
A. What will the final temperaure of the steel after quenching?
B. What is the amount of heat transferred from the steel to the water if the specific heat of steel is 452J/kg/K?
C. What is the mass of the water that remains in the water bath after the steel is quenched?
D. Before the steel is quenched how much heat would the smith have to add to the steel per second to keep it at the forging temperature of 1316C in a 35C room if the steel loses all of its heat through radiation? Assume the emissivity of the steel is 0.32 and the surface area is 0.11m2. The Stefan-Boltzman constant is 5.67x10^-8 W/m^2/K^4?
