    How to determine temperature rise in an outdoor, recirculation loop?

    IRStuff, I think I have it straight now. I have a heat load from convection, a heat load from ambient radiation and a heat load from solar radiation. The convection load I got from 3E Plus. The ambient radiation load I got from the Stefan-Boltzmann equation. It's the solar load that I'm...

    How to determine temperature rise in an outdoor, recirculation loop?

    Thanks for the reply regarding the 3E Plus program. I think I'll use the numbers generated by 3E and include that heat duty to the solar load. I've found some data for emissivity of SS pipe, along with the solar load of 350 BTU/hr.ft^2. When I use the 350 number, I get a much higher duty than...

    How to determine temperature rise in an outdoor, recirculation loop?

    Hi, I'm looking for some references to help me solve a problem that I have. We have an outdoor solvent tank which we intend to add a new pump loop to a building. The length of pipe will be 3000 ft to the building, and 3000 feet back to the tank. Hydraulically, we need to run 3" stainless...
