Supposing it is cooled to around 150 °F (and condensed to water), my steam table says about 1100 BTU/lb or 2.5 MJ/kg. 1 kWh = 3.6 MJ, so around 1.5 kg/h of 100 psi steam. The mass requirement would increase considerably if the return line temperature and pressure is closer to the inlet values.

To find the correct pipe size, go to the line for initial gas pressure reading 5 pounds. Now move to the right, until a number larger than 20,925 appears. In this case, the first greater number is 30,500. The number at the top of that column shows the appropriate pipe size, in this case …
