Hi, here's a problem I've recently come across, and it's bugging me that I can't wrap my mind around it.
I need to calculate the pressure of steam in a ∅12" pipe. I know that the steam flows at 8700 lb/hr over a 24 minute period, and that the average steam temperature is 176°F. I also know that the steam is not very superheated (if at all), and should be around 10-20 psi.
My question is: Is there enough information? If so, can someone point me down the right path? I haven't done thermo in a while.
EDIT: I posted this question before defining my problem. Here it is:-------------------------------------------------------------------------------------------------------
This is a non-mixing heat exchanger problem.

I also know that the steam is not very superheated (if at all), and should be around 10-20 psi. I have to find the pressure in the pipe, in addition to the volume of condensate 'released' if the steam gives up 6752 KW, which is the energy it takes to heat the mass of water described here:
Water flows in the cold side at 800 GPM (also over a 24 minute period) and must be heated from 110° to 170°F.
