Heating water

  1. Sep 27, 2003 #1
    To calculate the speed of heat projection we use the next formula:
    dQ/dt=A[alpha](T-To)
    what is does the [alpha] represents and what is the [alpha] of water?

    The equation you wrote describes a type of heat transfer. Alpha is a heat transfer coefficient, and A is the area of contact. Alpha isn't really a material property; although it may depend on some material properties as well as numerous other variables at the interface where heat is being transfered.
