What is the minimum cranking speed for a reciprocating S.I engine?
What is the minimum cranking speed for a rotary S.I engine?
What is special about the dark-field electron microscope micrograph?
What is the minimum cranking speed for a C.I engine with glow-plugs?
The relative magnitudes of the heterogeneous and homogeneous volume nucleation rate is given as 0.5. Calculate the factor C/C1 (the number of atoms on heterogeneous sites relative to the number within the matrix)? (Consider exp (?G*(hom) – ?G*(het)/kT) to be 1)
At very small driving forces, when activation energy barriers for nucleation are high, the highest nucleation rates will be produced by grain corner nucleation.
