MPa

They say the strength of NAC ranges between 40 MPa and 80 MPa, which is two to four times the strength of conventional concrete thus saving money and material.

The Hindu - Front Page 2010

In a paper published in the Geophysical Research Letters, they demonstrate that by May 2008, the reservoir had increased the stress on Yingxiu-Beichuan fault, one of the faults which ruptured during the quake, by 0. 01-0.05 MPa (or 0. 1-0.5 bar).

Peter Bosshard: The Dam That Shook the Earth 2009

Helium must be used at similar pressure (1000-2000 psi, 7-14 MPa) to maintain sufficient density for efficient operation.

Nuclear power reactor 2009

However, supercritical water around 25 MPa can give 45% thermal efficiency - as at some fossil-fuel power plants today with outlet temperatures of 600ºC, and at ultra supercritical levels (30+ MPa) 50% may be attained.

Nuclear power reactor 2009

Water or heavy water must be maintained at very high pressure (1000-2200 psi, 7-15 MPa) to enable it to function above 100ºC, as in present reactors.

Nuclear power reactor 2009

Supercritical water-cooled reactors: This is a very high-pressure water-cooled nuclear reactor that operates above the thermodynamic critical point of water (374C, 22 MPa) to give a thermal efficiency about one-third higher than today's light water reactors from which the design evolves.

Generation IV nuclear reactors 2009

The mixture is then molded at pressures of from about 150-600 psi and temperatures of from about 150-500 degrees Fahrenheit to yield a final composite having a compressive strength of at least about 5 MPa.

The supercritical water (25 MPa and 510-550ºC) directly drives the turbine without any secondary steam system.

Fast neutron reactors (FBR) 2009

The supercritical water (25 MPa and 510-550°C) directly drives the turbine without any secondary steam system, simplifying the plant.

Generation IV nuclear reactors 2009

Pressurised storage is the main technology available now and this means that at 345 times atmospheric pressure (34.5 MPa, 5000 psi), ten times the volume is required than for an equivalent amount of petrol/gasoline.
