Do you get wetter from walking or running in the rain?

Question

I always run because I want to get out of the rain faster, but I wonder if I’m just running into more rain and actually ending up wetter…

Answer 1

In chemical reactor design, we teach the students that the time you spend in the reactor is the ‘residence time.’ The goal of the class is to show you how to have the reactants in the reactor long enough to react completely without wasting time.

Think of running in the rain as your time that you are in the reactor. You need X number of minutes in the rain to get fully saturated. If you run, your time in the reactor is less, and you will be less wet.

So, run fast, spend less time in the ‘get wet reactor’ and get less wet.
