Because if I use basic conduction equation, i do not know what heat loss through the wall to assume. Since I only want to have one unknown which is thickness. All I want to know is if the hot face is this temperature, then using ceramic wool of certain density, conductivity and thickness. What...

Ladies and Gentlemen, I want to insulate a boiler furnace, with certain layers of ceramic and rock wool. I was told that suppliers have equations that I can use to calculate what the outside temperature would be, given a certain inside temp and the properties of the wool used. However I cannot...

Hi, I have designed a performance model for a steam cycle that has 7 bleeds and 3 turbines, using EES. I have reflected the changes in pressure at different bleed pts in the turbines using Stodola's Ellipse Law i.e. p_new = p_reference*(m_new/m_reference), where p is pressure and m is mass flow...

Hi, I have a set of 3 steam turbines placed in tandem, having 7 bleed points used for heating feedwater. If I decide to close any one of these bleeds, and want to maintain the nameplate capacity and not increase power output, what performance and operational issues should I investigate to...

I am writing a code on EES that simulates the exchangers in a boiler with hot air being flue gas, interfacing with water in the tubes. My aim is to see how raising the flow rate of water would reduce the air's temp. at the exit. my equation for this is...
