Title :The Electric Charge on Sprayed Oil Drops 2
Authors :Miyagi, Ken
Authors alternative :宮城, 健
Issue Date :Jun-1965
Abstract :Dependence of the quantity of the electric charge on sprayed oil drops upon the physical conditions at spraying and physical properties of the oil used was investigated. Using Millikan's oil drop method, fall time t_d and rise time t_u of oil drops were measured and then the quantity of the electic charge on the drops was estimated. Five kinds of lubricating oil with naphthene hydrocarbon structure as main constituent (these will be referred to as oils of group A, hereinafter) and other five kinds of lubricating oil with paraffin hydrocarbon structure as main constituent (these will be referred to as oils of group B, hereinafter), were sprayed to make the drops. The results of measurement showed no dependence of the electric charge on the drops upon the physical conditions at spraying and physical properties (except electric properties) of the oil used, but showed a definite difference between the quantity of charge on the drops of the oils of group A and the quantity of charge on the drops of the oils of group B.
