What is the Difference between diffusivity and mass transfer coefficient?
The rate of transfer of a process is equal to the driving force divided by the resistance.The mass transfer coefficient is the resistance to mass transfer. In mass transfer the driving force is the concentration gradient. The mass transfer coefficient is considered anything that contributes to resistance to mass transfer: thermal and eddy diffusivity, distance, etc.Fick's law of diffusion describes convective mass transfer as:N=-c*D*(ca2-ca1)/(z2-z1)where:-c is some constant multiplier (unitless)-The quantity (z2-z1) is the distance between two points. (length i.e. meters)-D is the mass diffusivity or the diffusion coefficient and is dependent on properties of the substance (such as particle size etc.) and temperature. (units: length2/time i.e. m2/s)-The quantity (ca2-ca1) is the concentration gradient between the same two points (the driving force) (units: amount/length3 i.e. mol/m3)-N is the rate of mass transfer (units: mass/(length2*time) i.e. mol/m2*s) )Putting Fick's law in terms of the mass transfer coefficient kc', yields:N=-kc'*(ca2-ca1)where kc'= -c*D/(z2-z1).You can see that the mass transfer coefficient is in fact a function of the diffusivity.

What is the difference between relative retention time and retention time?
Retention time is the time it takes for a compound to travel from the injection point to the detector in chromatography. Relative retention time is the ratio of the retention time of a compound to that of a reference compound in the same chromatographic system. It is used for comparing the behavior of different compounds on the same chromatographic column.
What is diffrente of retention time and ditention time?
Retention time is the time of passing material(fluids) through the volume of the drum with determined flowrate :Retention time=V/Qwhich Q : flowrateand V : Volumebut Detention time is the time that materials stay in drumin batch systems Detention time equals with Retention time.but in continious systems or semi batch systems denention time is bigger than Retention timecommonly.Detention time= n Retention timewhich n is the number of times which materials(fluids) pass through the the volume of drum.

What is the time difference between Singapore and yunnan?
There is no time difference between Singapore and China.
Can relative retention time changed?
Yes, relative retention time can change based on various factors such as changes in column temperature, flow rate, and mobile phase composition. These changes can affect the interaction between the analyte and stationary phase, thereby altering the relative retention time.
