This is a virtual experiment in which one explores evaporative cooling. At the bottom of the canvas is a beaker with 1000 mL of water. To the left of the beaker is a valve and pump. The pump can be turned on using the black switch labelled "PUMP POWER". Once the system has gotten to steady-state, the fan can be turned on by clicking the black switch in the upper-right corner labelled "FAN POWER". Thermocouples are placed at the bottom of the beaker, on the distributor, at the water outlet, and in front of and behind the fan. The accompanying worksheet to this experiment can be downloaded by clicking the "Worksheet" button on the drop-down menu. Reset the simulation at any time by pressing the "Reset" button, and change units by pressing the "°C / °F" button.

This digital experiment was created in the Department of Chemical and Biological Engineering, at University of Colorado Boulder for LearnChemE.com by Neil Hendren under the direction of Professor John L. Falconer and Michelle Medlin. It was prepared with financial support from the National Science Foundation (DUE 2336987 and 2336988) and is based on a scientific article and accompanying worksheet protocol developed with separate support under NSF 1821578 led by Washington State University.
