Nozzle jets or nozzle jets with telescopic drives used in vehicles with high-pressure headlamp washer systems.
Purpose. This standard stipulates the requirements, test conditions and test procedures for function, material and durability testing of nozzle jets, as well as nozzle jets with telescopic drives, used in vehicles with high pressure headlamp washer systems (referred to...
INTRODUCTION This Item provides a computerized method for predicting pure jet flyover noise spectra from noise spectra measured from, or predicted for, a stationary jet. The changes in noise levels from static to flight conditions are often referred to as static-to-flight effects. The...
A computerized method for estimating exhaust noise spectra from a database is provided. The variables considered in the interpolation/extrap
ESDU 72002 gives a method of estimating the near field sound pressure levels due to high velocity jet noise from a single stationary conical nozzle. From a comparison with measured data, the accuracy of the estimated levels is expected to be within 5 dB, i.e. between approximately 60...
ESDU 89041 gives a graphical method for estimating overall and one-third octave band sound pressure levels as a function of observer distance and angle to the efflux plane, jet pipe diameter, and jet temperature and velocity. The data are also given in 10 tables, each for a fixed...
ESDU 13001 provides a means of estimating shock noise levels in one-third octave bands emanating from a supersonic jet. The prediction program accompanying this Item covers both near and far fields and is applicable to a static nozzle. The main input parameters that need to be...
INTRODUCTION This Item provides a computerised method for estimating exhaust noise spectra in one-third octave bands from a given database. The procedure is an interpolation/extrap
ESDU 67035 presents non-dimensional mass flow and gross thrust parameters as functions of total pressure/ambient pressure ratio (up to 50) and ratio of specific heat capacities (from 1 to 1.67) for one-dimensional jets exhausting isentropically into the atmosphere. The data relate primarily...

Work specified (shotcreting processes)-The work should be classified as either structural or nonstructural. Shotcrete having a specified compressive strength of 4000 psi (28 MPa) or greater is considered structural shotcrete. Shotcreting can be applied by one of two processes: wet-mix or dry-mix....

This International Standard specifies the dimensions and execution of strips for water nozzle solidification including their designation.
1.1 This test method covers a test that can be used to compare the cavitation erosion resistance of solid materials. A submerged cavitating jet, issuing from a nozzle, impinges on a test specimen placed in its path so that cavities collapse on it, thereby causing erosion. The test is...
1.1 This practice covers the determination of material loss by gas-entrained solid particle impingement erosion with jet- nozzle type erosion equipment. This practice may be used in the laboratory to measure the solid particle erosion of different materials and has been used as a...
