Hi,
Could someone tell me (or point me at a resource or standard) that can identify the difference between surface roughness measurements Ra and AA (Average Roughness). I have values in both scales, and need to compare them for a model I am building.
Hi,
I am currently modelling a heavy oil system that uses a Return Flow atomizer. Basically a pump is used to pump oil to a gun. At the tip of the gun, the oil is swirled and either discharged through an orifice into the burner, or returned through an opening back to the pump inlet. Pump...
Hi,
I am building a computer simulation of a forced circulation boiler, and have a few questions. Can someone explain the purpose of circulating pump injection water? Is it for sealing the pump? It appears that some of the injection water bleeds/leaks into the circulating water ... is this...
Hi,
I am doing a dynamic simulation of a fan for a power plant simulator and am trying to calculate the required power at a dead head or run out condition.
Given the general power equation:
HP = (CFM * Head * K )/(K2 * Eff)
Where
CFM is fan flow
Head if fan pressure differential or head...
