  2. Types of concrete - Wikipedia

    en.wikipedia.org/wiki/Types_of_concrete

    The ingredients in any particular mix depends on the nature of the application. Regular concrete can typically withstand a pressure from about 10 MPa (1450 psi) to 40 MPa (5800 psi), with lighter duty uses such as blinding concrete having a much lower MPa rating than structural concrete. Many types of pre-mixed concrete are available which ...

    RD-0126 - version of the engine with conventional de Laval nozzle. Chamber pressure 5.89 MPa (854 psi), mass 240 kg (530 lb), specific impulse 470s. [2]

  5. .357 SIG - Wikipedia

    en.wikipedia.org/wiki/.357_SIG

    According to the C.I.P. rulings the .357 SIG case can handle up to 305 MPa (44,236 psi) piezo pressure. In C.I.P. regulated countries every pistol cartridge combo has to be proofed at 130% of this maximum C.I.P. pressure to certify for sale to consumers. The SAAMI pressure limit for the .357 SIG is set at 275.80 MPa (40,000 psi), piezo pressure ...

    The Helium is stored initially at 34.32 MPa (4,978 psi) and is regulated to 1.75 MPa (254 psi), with a maximum pressure of 2.15 MPa (312 psi) and a minimum of 1.37 MPa (199 psi), which is the minimum required pressure to activate the pneumatically actuated valves of the SKD. [1]

  7. 6.5×47mm Lapua - Wikipedia

    en.wikipedia.org/wiki/6.5×47mm_Lapua

    High pressure level (435.00 MPa (63,091 psi) P max piezo pressure) and cartridge case capacity enables relative high velocity and flat trajectory. Reduced barrel wear [ 5 ] compared to 6mm Norma BR The 6.5×47mm Lapua has a base diameter and overall length similar to the 7.62×51mm NATO / .308 Winchester , allowing it to accept the same bolt ...

  8. FN 5.7×28mm - Wikipedia

    en.wikipedia.org/wiki/FN_5.7×28mm

    This means that 5.7×28mm chambered arms in C.I.P. regulated countries are currently (2018) proof tested at 4,313 bar (431 MPa; 62,555 psi) PE piezo pressure. [7] Despite the relatively high Pmax the bolt thrust of the 5.7×28mm is on a similar level when compared with traditional service sidearm cartridges.
