Homework Help: Calculate time constant from the slope of dimensionless temperature vs time graph.

  1. Jan 31, 2007 #1
    Given:

    slope of the graph of ln(temperature dimensionless) vs. time

    slope=-0.0416

    -t/tau = ln(temperature dimensionless)

    I dont know where to put the slope into the equations?

    I know that the time constant is the tau.

    Also have -1/tau equation.

    I tried this:

    -(1/0.0416) = 24.04 sec is this the time constant?

    nevermind i figured it out.

    m=-1/tau

    and the slope is given
