    Calculating Nusselt No. for Natural Gas Pipeline

    I am trying to find temperature distribution inside the pipe. I guess nusselt number associate with the flow of the liquid and it take convective heat transfer co-efficient within the fluid and not between wall and fluid, please correct me if I am wrong.

    Deriving Joule-Thomson Effect: CNGA Approximation

    Hello ALL, I am looking for the derivation of joule thompson effect to show that Uj = (nBTave^-n / Roh(ave) Cp) *Zave where n = 3.825, B = 5287.Pave.10^1.785G Pave in KPa(g) and Tave in K using CNGA approximation. Can anybody help me in this? Thanks Shabbir

    Calculating Nusselt No. for Natural Gas Pipeline

    Hello I need to calculate the nusselt number for natural gas in a buried pipeline. My question is how to calculate the convective heat transfer co efficient? The data is 220000m3/h, pipe ID 35", gas temperature 100C and ground temperature is 4C, gas SG 0.65, k = 0.037 W/m-K, R= 441 J/kg-K, CP =...
