Relationship between real manufacturing precision of fire nozzle and its water jet trajectory geometric characteristics

Abstract

In present paper showed the methodology, grounded, evaluated, illustrated and described by formulas influence of manufacturing precision of the fire barrel outlet hole diameter of which do not meets the regulatory and established requirements in varying degrees on its water jet trajectory geometric characteristics, namely the distance of the flight and height of lifting, for various values of inclination angle of the barrel axis to the horizon, both in absolute and in relative terms. Expedience of beta distribution using for describe these variables taking into account the non-linearity of their dependence on each other was grounded.
