How do I calculate the heat transfer coefficient for pipe heat loss in Excel?

AI Thread Summary
To calculate the heat transfer coefficient for pipe heat loss in Excel, the resistive analogy is a useful approach. Key parameters include pipe diameter, thickness, thermal conductivity (K value), and temperature differences. Insulation properties, including thickness and thermal conductivity, also play a crucial role in the calculations. Reference materials, such as Wikipedia, can provide additional insights into the heat transfer coefficient of pipe walls. This method aims to streamline the estimation process for general use.

Hi there,
I am trying to make a spreadsheet which calculates the heat loss through a pipe and also heat loss when insulated, I am using the resistive analogy to calculate this and I have it working, the only problem I am having is the heat transfer coefficient, how do I calculate this?

I know the pipe diameter, thickness, K value, temperatures inside and ambient and the insulation thickness, k value and diameters.

it is just for general use, to get an estimate and save time.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
