Basic Math Check for the Heating of 304 Stainless . . . 3

[AlbertG]

Hello folks.

Ran out of fingers and toes; and just needed a little help with some simple heating work on a small amount of 304 stainless (8000 kg/m³; 500J/kg.K (0-100°C) --

http://www.azom.com/details.asp?ArticleID=965).

Here's what I have.

First, I am working with what amounts to a cylindrical can; 5.25" diameter X 6" tall, with an .035" wall. The heat source is entirely from within; and is capable of uniformly raising the temperature of the body from 25ºC to 1200ºC in 35 seconds (still air).

Question: Is the basic Q = mc(?T) equation appropriate to call in consideration of the material specs/configuration?

If so, I seem to have come up with a value of about 13kW as the heating energy represented here. Correct?


Thanks again.

You've been given answers that address your problem.

Just do the math. What is the temperature at each second, what is the loss at that time?
