The kilobar, equivalent to 100 MPa, is commonly used in geological systems, particularly in experimental petrology. The abbreviations "bar(a)" and "bara" are sometimes used to indicate absolute pressures, and "bar(g)" and "barg" for gauge pressures. The usage is deprecated but still prevails in the oil industry (often by capitalized "BarG" and ...
The current depends on the number of ions, which depends on the pressure in the gauge. Hot cathode gauges are accurate from 10 −3 Torr to 10 −10 Torr. The principle behind cold cathode version is the same, except that electrons are produced in the discharge of a high voltage. Cold cathode gauges are accurate from 10 −2 Torr to 10 −9 ...
The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa = 0.145 ksi. The megapound per square inch (Mpsi) is another multiple equal to a million psi. It is used in mechanics for the elastic modulus of materials, especially for metals. [5] The conversion in SI units is 1 Mpsi = 6.895 GPa, or 1 GPa = 0.145 Mpsi.
cdrtools (formerly known as cdrecord) is a collection of independent projects of free software/open source computer programs for CD and DVD authoring.. The project was maintained for over two decades by Jörg Schilling, who died on October 10, 2021.
A diver with a RMV of 40 L/min at 50 msw (6 bar) for 10 minutes will consume 40 × 6 × 10 = 2400 litres of free air – the full capacity of a 12-litre 200 bar cylinder. Imperial examples: A diver with a SAC of 0.5 cfm (cubic feet per minute) at 100 fsw (4 ata) will consume 0.5 × 4 × 1 = 2 cfm surface equivalent.
The test is performed by loading steadily at a rate such that K I increases from 0.55 to 2.75 (MPa)/s. During the test, the load and the crack mouth opening displacement (CMOD) is recorded and the test is continued till the maximum load is reached. The critical load P Q is calculated through from the load vs CMOD plot.
As of 2022, most supercritical power plants adopt a steam inlet pressure of 24.1 MPa and inlet temperature between 538°C and 566°C, which results in plant efficiency of 40%. However, if pressure is further increased to 31 MPa the power plant is referred to as ultra-supercritical, and one can increase the steam inlet temperature to 600°C ...
