This simulation will run on your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter. For this simulation, a screencast is provided to explain how to use it.

Simulation: Reading a Psychrometric Chart

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. If the dry bulb temperature increases (without changing the moisture content), how does the relative humidity change?
  2. If the dry bulb temperature increases at constant relative humidity, how does the enthalpy of the air (+water vapor) change?
