How does Build To Order work for car manufacturers? Why would you only build a unit when it is ordered, rather than build units, stock and sell, when unit numbers are so high. This isn't my field so I need some basics.
I have been asked to compare the merits of installing an automatic explosion isolation valve (actuated on rate of change of pressure and IR camera), compared to a crimped ribbon detonation flame arrester. Extended burning is not an issue.
Medium is saturated methane+air with light particulate...
Does anybody know the upper and lower explosive limits of methane at elevated pressures? I am working with mines gas which is an air+methane mix. I know that the LEL and HEL are 5-15% at atmospheric pressure, but I also know that as the gas is compressed the higher explosive limit rises.
