Thermal Energy Applied

  1. Aug 19, 2014 #1
    I want to calculate the energy applied to a slab of steel with a temperature rise that varying with time (t) as -
    13t + 5t^2 + 10* sin (3ωt)

    The energy applied to the system is calculated by mc (dT) equation where
    m mass of the slab
    c specific heat
    dT change in temperature

    Are m and c constant?

    Then [itex]dt= 13+ 10t+ 30\omega cos(3\omega t)[/itex], of course.
