  • FUNDAMENTALS OF HYDROGEN IGNITION and HIGH

    2008-7-19 · •Ignition pressure is very high for the case of the initial pressures higher than 5 MPa probably due to near supercritical conditions. •The cases of the initial pressures; 1.o, 2.0, and 3.0 MPa, need less ignition pressure due to high sensitivity for such cases.

  • Nebulisers: their effectiveness, indications and limitations

    source generates air or gas that is forced through a narrow hole (ven-turi) as a high-velocity jet. An area of low pressure occurs immediately adjacent to this jet that passes over a narrow liquid feed tube. Drug solution is sucked up from a reser-voir below the feed tube and atom-isation of the solution ensues. 1 The jet…

    2013-5-28 · the air varies inversely with cross sectional area. 2.2 FLUID PRESSURE 2.2.1 The cause of fluid pressure Section 2.1.1 described the dynamic behaviour of molecules in a liquid or gas. When a molecule rebounds from any confining boundary, a force equal to the rate of change of momentum of that molecule is exerted upon the boundary.
