ANTI-EDIT-QUEUE:::::: This proposed convection heater is designed for tobacco products only. If you are under the age of 18 or the consumption of tobacco products is illegal in your area do not read this question.

I am designing a convection hea ter for an Arduino. The basic design of this heater will be to have a fan blow room temperature air across a heated coil. The air will need to be heated to 250–300 degrees C. In order to control t\he temperature of the coil I will have a sensor located just before the product to be heated. The sensor will cycle power to the coil on\\off to maintain the desired temperature. The air wil l flow through a tube the size of a quarter (about 25mm diameter).
Given the above informAtion what are my CFM requirements? Please explain the equati on used as I would like to understand the theory behind this.
Here is my intended des ign
Using Fluther
