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

Abstract

In present paper showed the methodology, grounded, evaluated, illustrated and analytically described by formulas influence of manufacturing precision of the fire nozzle outlet hole diameter of which meets the regulatory and established requirements 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 nozzle 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.
