Why does the minimum in a plot of plate height vs flow rate occur at lower rates with liquid chromatography than with gas chromatography?
Longitudinal diffusion is much more important in GC that in LC. Longitudinal diffusion is a large contribution to H at low flow rates. The initial decreases in H in plots of plate height vs. flow rate are thus largely the result of longitudinal diffusion.. Because gaseous diffusion coefficients are orders of magnitude larger than liquid values, the phenomenon becomes noticeable at higher flow rates in GC than in LC. The minimum is sometimes not observed at all in LC.
What viscosity level was the fluid flow rate the highest?
The relationship between radius and fluid flow rate is inversely proportional. As radius goes down, fluid flow rate goes up. The highest fluid flow rate will be at the lowest radius.
How does heat affect lava flow?
Heat effects the flow rate of lava because the hotter the lava is, the less viscous it is which allows it to flow faster than if it had a slow flow rate. If it has a low temperature, then the flow rate will be much slower because it has a high viscosity.
When can you increase the flow rate of a fluid in your daily life?
The flow rate of a fliud or liquid could be increased (depending on the situation) by increasing the amount of the fluid, then channelising this fluid into a narrow channel.
What is the rate at which electrons do work?
Current. The flow of electrons is the flow of a moving charge. The rate of flow is current (the amount of charge that flows in a set time). The equation is: I = Qt Hope this helps.

How is a body of water's rate of flow related to its rate of deposition?
As the rate of flow decreases, the rate of deposition increases
What is The rate at which liquids flow is called?
Viscosity is the term.
Which DNA nucleotide pair is most stable?
GC pairing is most stable and require maximum energy to dissoicate. This is reason that rate of DNA denaturation depends upon the GC content of DNA.
What viscosity level was the fluid flow rate the highest?
The relationship between radius and fluid flow rate is inversely proportional. As radius goes down, fluid flow rate goes up. The highest fluid flow rate will be at the lowest radius.
How is viscosity related to flow rate?
Viscosity is a substances resistance to flow. So as the viscosity of a substance increases, the flow rate will decrease.
What is the relationship between flow rate and radius size?
Flow rate= radius to the fourth power
How does viscosity relate to flow rate?
High viscosity lead to a low flow rate and inverse.
Is there a flow rate of a solid?
The FRI, or Flow Rate Index is a rating system for the flow rate of solids. Air and air pressure measurement connections are part of the testing apparatus.
Does static pressure affect flow rate?
Static pressure certainly does affect flow rate. Static pressure can slow or speed up flow rate based on the liquid.
What relationship exists between temperature of oil and flow rate?
higher temperature lower flow rate.
Why does the theoretical flow rate differ from the actual flow rate?
gravity,temperature type of fluid,pressure
