Chapter 3, Problem 3.120P
As fresh-poured concrete hardens, the chemical transformation releases energy at a rate of 2 W/kg. Assume that the center of a poured layer does have a heat loss of 0.3 W/kg and that it has an average specific heat of 0.9 kJ/kg-K. Find the temperature rise during 3 hof the hardening (curing) process.
