✦ Synopsis

The effect of pressure on the burning veloc~ity of four fl~el-air dnd three fuel-oxygen mirture.~, all il, stoichiometric proportions, wa~ determined using the constant-rolume bomb method. Ionization gaps were employed to obtain Che flame radius/time dat,t. The pressure range ;nveuligette d wa., from O" 2 to 20 atmospheres. Burning velocity values were calculated from flame speed measurement.~ using th; recently developed equations of Eschenbach and Agnew. Possible sourc,_~s of errors which are peculiar to the ionization gap technique of measuring flame speeds are discussed along u'ith the preeautiow; taken to minimize their effects.
