Because you could not get this volume of steam or water to flow through the heat exchanger if the pressure were 0.0 barG (1 atm). The pumps have to push the water (or steam) and this raises the pressure above 1 atm. Murray explained this in Exhibit 5: The steam pressure was reported (for the entire period) to be 0 kPaG and the piping is DN40. For steam to flow, a pressure differential is required to overcome the losses in the pipe. Given the foregoing, this would require that the pressure on the JMP side of the building was significantly below atmospheric (vacuum) and that the steam would flow at extraordinary velocity. But this was obviously not the situation present at the location. I and others noted this fact before reading this Exhibit. (Let us assume this is meant to be 0.0 barG, and the 0.0 bar in Rossi's data is a misprint.) Also, because an earlier version of the report supposedly had higher numbers, which were replaced with 0.0 bar in the later version. I saw only the later version. - Jed
