INTRODUCTION Long time readers may recall that one answer to the question of how humidity changes the thermal conductivity of air is “Nothing to worry about” [1]. Generally, the effect of humidity on air properties is small enough that it can be neglected. However, at high ambient temperatures and low pressure, humidity effects may need to be addressed in applications such as … [Read more...]
Calculation Corner: A Simple Method for Estimating Radiation Heat Transfer
This article describes a semi-empirical equation that can be used to assess radiation heat transfer in terms of an effective convection coefficient. The effective convection coefficient due to radiation is shown to be: Where temperatures are in °C and ε is the emissivity of the radiating surface. This equation is accurate to within ~10% over a temperature range of 0 - … [Read more...]
Bad Data!
Overview Sometimes, regardless of how carefully we conduct testing to gather data, we end up with results that just seem wrong. This could be a sign that we have stumbled upon an earth-shattering breakthrough that will change the world’s understanding of fundamental physics1 …. or, it’s possible that a mistake in the testing led to bad data. This column will discuss a few … [Read more...]
