Peak overpressure will usually be different on each face of the building with the highest being on the face directly opposing the blast source.
Properly select the blast damper for the specific blast peak overpressure and impulse duration of the project.
Simultaneously with experiments in the overpressure vessel, some experiments with the low-pressure based water jets were performed with nozzles Lechler 1508 having the following parameters: the vertex angle of the outlet jet--30[degrees], the nozzle outlet diameter--2.
Also, because the pressure sensor has failed, there is no easy way to trace the cause of overpressure.
Or the calibrated range or span can be compressed from 100 percent to 10 percent of the rated range, providing higher overpressure capability at a lower pressure range.
The study was confined to a realistic, worst-case scenario of engine surge, which yields the greatest inlet overpressure response.
The first task was to develop a methodology using two-dimensional unsteady CFD to obtain the ultimate-strength, peak inlet overpressure distribution.
This flight condition produces the ultimate magnitude of surge-induced hammer-shock overpressure for the F-16 NSI with an F100-PW-200 engine.
can be predicted with the overpressure of the incident and not the reflected shock front, [P.
The above conclusions allow to make the further statement, namely, the non-linear relationship will exist also between the overpressure Pi)max and the dynamic mechanical properties of steel and concrete.
