Natural gas with a specific gravity of 0.7 and flowing with a flowrate of 2 MMSCFD in a split pass coil line heater. Line Pressure and temperature (before the choke and the line heater) = 3000 psia, 100F. Well shut in pressure = 5000 psia Pressure after choke = 1500 psia.
a) Gas was heated hot enough so that it drops to hydrate temperature after the choke. What was the temperature it was heated to, before it enters the choke?

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
