Rasbash, D.J. and Rogowski, Z.W., 1956. THE VENTING OF GAS AND VAPOUR EXPLOSIONS IN DUCT SYSTEMS PART 1 EXPLOSIONS OF PENTANE VAPOUR-AIR MIXTURES IN A CLOSED TUBE 6FT LONG X 6 IN DIAMETER. Fire Research Notes 257
ABSTRACT
A series of measurements has been made of the pressure developed in explosions of pentane-air mixtures in a closed tube 6 ft long x 6 in. diameter. A maximum pressure of 94 p.s.i. was found to occur in mixtures containing 3.4 - 4.0 per cent of pentane. The initial stages of the pressure time-record were more reproducible when a spark was used as an ignition source, than when a proprietary safety fuse was used.
