Abstract: The uncertainty of average measurements has been investigated, and a generalized formula for the standard deviation of spacial and time average measurements has been derived. The special cases ...

Abstract: The effect of probe blockage on the free-stream pressure and Mach number has been studied for the two limiting cases of open free jets and closed tunnels. Cylinder probe calibrations carried ...

Abstract: The paper describes the development of a moisture probe using the principle of laser light attenuation. The probe response was calculated for various droplet sizes and steam conditions. A ...

Abstract: The history of pipe wall tap nozzles and throat tap nozzles, as to performance characteristics, is briefly reviewed. A series of tests was conducted on pipe wall tap and throat tap nozzle ...

Abstract: Various statistical relations, as applied in instrumentation in general, and as required in Performance Test Code (PTC) work in particular, are summarized in this paper. These concepts are applied ...

Abstract: In this paper, we first present a state of the art review of the published work concerning theoretical nozzle discharge coefficients. Then, we develop a new nozzle discharge coefficient based ...

Abstract: A generalized rational equation is derived for the discharge coefficient of differential pressure-type fluid meters. Its factors are particularized for throat tap meters, pipe wall tap nozzles, ...

Abstract: The effect of inlet edge roundness on the discharge coefficient of an orifice plate is studied experimentally. Several methods for measuring edge roundness are discussed and applied. An optical ...

Abstract: Generalized solutions are developed for the flow across an abrupt enlargement. Three cases are considered, namely; an incompressible fluid, a subsonic compressible fluid, and a compressible fluid ...
