Calculation Corner: Properties of Humid Air

 

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...]

The Effect of Ambient Conditions on Local Climate Inside a Pump Electronics Enclosure

 

By: Parizad Shojaee Nasirabadi, Jesper H. Hattel INTRODUCTION Condensation and moisture related problems are the cause of failures in many cases and consequently serious concerns for reliability in electronics industry. Therefore, it is important to control the moisture content and the relative humidity (RH) inside electronics enclosures. Understanding the transport … [Read more...]
