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

jrodmckis

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?

jrodmckis

nevermind i figured it out.

m=-1/tau

and the slope is given
