Calculating Friction Factors for High Pressure Steam Flow?

AI Thread Summary
To calculate the friction factor for high pressure, turbulent steam flow, one must consider the Reynolds Number, pipe inner diameter (ID), and surface roughness. The Moody Diagram can be adapted for these conditions, providing a practical reference for friction factors. The Reynolds Number is influenced by the steam's density, velocity, ID, and viscosity, which should be determined for the specific flow conditions. Accurate calculations require understanding these fluid properties to ensure reliable results. Utilizing these principles will aid in effectively managing steam flow in high-pressure systems.

How does one find the friction factor of a high pressure, turbulent steam flow? Is there a Moody Diagram equivalent for these fluid conditions?

The Moody Chart or correlations may be applied for practical purposes.

Your friction factor will be a function of Reynolds Number, pipe ID, and pipe surface roughness.

The Reynold's Number depends on density, fluid velocity, ID, and viscosity. You can determine these properties for your flowing steam conditions.
 
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...
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...
