Lower temperatures favor Coble creep and higher temperatures favor Nabbaro–Herring creep because the activation energy for vacancy diffusion within the lattice is typically larger than that along the grain boundaries, thus lattice diffusion slows down relative to grain boundary diffusion with decreasing temperature.
Answer:
The simplest differential form of Fick's flux equation for water vapor is
Explanation:
Fick's law has to do with the density of the particles is proportional to their concentration gradient. For this question some assumptions will be taken into account:
-The pipe is considered to be very long and diffusion only occurs in the r direction.
-The reaction is not homogeneous, therefore RA = 0
-The concentration of the component A is constant
-No mixing, only diffusion
Due to the complexity of the terms used in solving the Fick equation, the solution is found in the attached file.
Answer:
design hour volumes will be 4000 to 6000
Explanation:
given data
AADT = 150000 veh/day
solution
we get here design hour volumes that is express as
design hour volumes = AADT × k × D ..............1
here k is factor and its range is 8 to 12 % for urban
and D is directional distribution i.e traffic equal divided by the direction
so here design hour volumes will be 4000 to 6000
