I guess our “tank” comment was a little obvious…but what was inside the tank—not so much.
Answers: Image is of a tank—however, contrary to what most of you guessed, it is filled with cement powder! The image is from our very own, John Pratten, which was taken at 9:30am on the East side of the tank. You can definitely note the morning effects of the sun, and if you look even closer, you can tell where the level of cement powder (dark blue) is as well. The purpose of this image was to validate the level of the tank. As a thermographer, you need to find the optimum time to scan a tank due to the thermal cycling that takes place.
