Specific heat help -- cooling down a metal bar

[QUOTE="Don9of11, post: 5483139, member: 595184"] I'm a design draftsman, I have bar of 17-4 stainless steel it weighs 6.9 lbs. The Product Data Sheet shows a specific heat 0.11 (BTU/lb/F (32-212F) ([URL="http://www.aksteel.com"]www.aksteel.com[/URL]) It's at room temperature or 70 degrees F. I want to cool the bar to 50 degrees F. The surface area of the bar is 245 sq. inches. The bar is then immersed in pure water and the water temperature is 50F. How long will it take to cool and how many BTU's are used? I'm trying to put the answer in simple terms and so I'm looking to get a simple equation that let's me say "it takes (X) amount of minutes or hours to cool and it takes (X) amount of BTU's". Thanks [/QUOTE]
