Abstract
A QUICK survey of the hydraulic aspects of the vapor lock problem is given here by Mr. Pigott.
The hydraulic design of the supply system from the tank to the fuel pump is discussed by the author.
The cause for carburetor vapor lock beyond the fuel pump becomes very largely a question of the ability of control orifices of any type to measure mixtures. In general, control orifices can only measure a homogeneous fluid correctly.
The general methods of calculating a system for obtaining the limiting tank temperature for take-off and the limiting altitude for any system, are discussed, and the requirements summarized.
