Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Engineering - Department of Mechanical Design and Production Summary: Measurement standards for dynamic pressure and its traceability to the International System of Units (SI) is a novel field in metrology. Therefore, such standards are not commonly found in National Metrology Institutes (NMIs) that could enable calibration of modern dynamic pressure transducers. For several industrial fields using dynamic pressure technologies, this, in turn, limits quality assurance.Due to, the lack of traceability in the dynamic pressure measurements, the dynamic pressure sensors and transducers are calibrated using static or quasi-static methods. This may lead to significant errors in measurements as the behavior of the sensor in the dynamic mode differs from the static mode.In response to this problem, this study has been dedicated to establish and investigate a primary standard system for dynamic pressure measurements up to 100 MPa with relative uncertainty as low as 1.5 %. This new reference dynamic pressure standard is of crucial importance to develop calibration methods for dynamic pressure transducers. Furthermore, it provides the metrological basis for the dynamic pressure technologies such as automotive industries, military, aerodynamics, medicine, and material testing
