Mr. Atkinson is on trial is on trial for criminal negligence because his company’s steam boiler exploded. Mr. Atkinson’s job was to monitor the pressure in the boiler to make sure that it does not go above the safe limit of 6895kPa gauge. He testifies that just before the explosion, his control panel showed that the pressure was 5860kPa gauge, the temperature was 400oC, and the specific volume was 0.037 m3 per kg. All gauges were tested and found to be functional during the investigation following the explosion. The prosecutor says that Mr. Atkinson fell asleep while on duty. As a technical witness, what can you say about the case? Use the table below to get the specific gas constant of the steam.
