CASE STUDY Mr. Atkinson is on trial for criminal negligence because his company's steam boiler exploded. It was Mr. Atkinson's job to watch the pressure on the boiler to make sure that it does not go above the safe limit of 6895 kPa gauge. He testifies that just before the explosion, his control panel showed the pressure was 5860 kPa gauge, the temperature was 400°C, 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 Atkinson fell asleep while on duty. As a technical witness, what can you say about the case? Refer to Table 3.1 for the specific gas constant of steam.
