  7. It is the amount of deviation from the ideal gas equation of state, PV=nRT. Adding the compressibility factor, Z, yields PV = Z nRT If the compressibility of some quantity of air n=1, at 30 Bara is 0.82 and 273 °K, then its volume will be V = 0.82 x n x R x 273 / 30, or 82% of the volume of an ideal gas. Where R is the universal gas constant. https://en.m.wikipedia.org/wiki/Compressibility_factor
  8. Gasoline, or petrol, ignites too soon (predetonation) in a diesel engine due to diesel engines high compression ratios. That causes some reverse loading, very high stresses, mostly on the cylinder rods which may eventually fail in high compression load and bearing wear. Multifuel engines must be designed for extra high rod loads.
  9. The first part of the question is comparing two completely different pipe lines of different diameter. The small pipe diameter needs more pressure to move the same flow rate. Bernoulli principle applies to points within the same pipe line. When both pipes are within the same pipeline pressure is lower in the small diameter pipe, but compared to what? Compared to the larger pipe upstream, the pressure will be lower. Why? Because energy (in this case pressure, or potential energy, from an upstream point must be used to accelerate the fluid as it moves into the smaller area of a smaller diameter pipe. So the pressure there in the smaller diameter pipe will be lower than the upstream point, but velocity will also be higher. Potential energy was converted to kinetic energy, which has increased just as much as its potential energy (pressure) has decreased. Should the next part of the pipeline get large again, then the small pipe's kinetic energy from its high velocity will be converted to higher pressure as the velocity slows down and enters the large diameter. To make this all right and proper, you must think in terms of total energy, which is always the same in pipes of both large and small diameters, as long as they carry the same flow rate and that there will be variations of how much of that energy is kinetic and how much will be potential energy when you have changes of diameters in the same pipeline.

  16. You’re all right, but there are multi fuel outboard engines (based on petrol engine design) used in defence running on various fuels, kerosene, jet fuel or diesel (low compression ratio with spark plug support). Downside is that the engines are not compliant to enviro regulations, due to incomplete combustion (engines are “Smokey”). See Mercury Racing Optimax JP and Evinrude E-TEC.
  17. Compression Ratios are also very different, Diesel run with compression ratios from 17~21 to 1 where gasoline engines can only run at compression Ratios of 8~11 to 1. Gasoline will detonate at much lower compression than what is needed for diesel to reach self ignition point. A real diesel engine will be more efficient overall since it will have the ability to operate at higher compression ratios. If a petrol engine were to have the same compression ratio, then knocking (self-ignition) would occur and this would severely reduce the efficiency, whereas in a diesel engine, the self ignition is the desired behavior.
  18. So many change quality efforts fail because too much effort is put into the technical change while not enough effort is put into ensuring acceptance of the quality effort. Resistance is to be expected. Thus, the need for the quality effort must be established and a vision of what a Six Sigma organization looks like must occur. A key element of the change initiative is mobilizing commitment to the Six Sigma organization. This means identifying the sources of resistance to Six Sigma and planning a strategy to overcome that resistance is important. With the above opening thoughts, I welcome you all in six sigma blog.... We are here to begin the new journey. and I welcome you with your expert experience & questions
