Chad - Seems like a rather odd requirement but your number is correct Length * width * pressure 2" x 2" * 10 psi = 40 Or if you knew the pressure applied and wanted to know what the part saw: pounds per square inch or Pounds / square inch 40 / 4 = 10 You might use the latter example to tell your customer you accidently set the press pressure to 50 psi which resulted in 12.5 psi on the part. >From: Chad Haima <[log in to unmask]> >Reply-To: TechNet E-Mail Forum <[log in to unmask]>, Chad Haima ><[log in to unmask]> >To: [log in to unmask] >Subject: [TN] I hope this isn't a dumb question >Date: Thu, 10 Feb 2005 08:26:11 -0800 > >Technetters, > >I have a customer that wants 10psi applied to a roughly 2 inches squared >heatsink.
