Liquid natural gas (LNG) ships have a boil-off rate of about 0.3 percent per day. For a ship of 50,000-m3 capacity, calculate the daily mass of natural gas released by boil-off, treating the LNG as methane stored in transport at 125 kPa and -126°C. What volume does mass of the boiled-off natural gas occupy if the temperature is 15°C at 100 kPa pressure, assuming ideal gas behavior?
