What is the difference between heat transfer and mass transfer?
Heat transfer deals with the movement of heat and temperature gradients. The three types of heat transfer are conduction, convection, and radiation. Mass transfer deals with concentrations of a particular substance. Types of mass transfer include diffusion and convection.
Does the mass of an object determines the rate at which it will fall?
Mass does not determine the rate something will fall. The rate of acceleration is constant as gravity, regardless of mass.
What is the rate of energy transfer called?
It's Power.
How is the average rate of heat transfer calculated?
when is heat transferred?
How can you maximise the rate of energy transfer to keep things cool?
you can maximise the rate of energy transfer by using materials that; -are good conductors -are painted Matt black -have the air flow around them maximised
How would bigger mass in the water affect the cooling rate?
Say you are cooling liquid A with water. The rate of heat transfer is given by Q = mH2OCpH2OdTH2O = mACpAdTA, where m is the mass, Cp is the mean heat capacity and dT is the change in temperature. So, if you increase m, the mass of water, Q increases (the rate of heat transfer increases) and hence the cooling rate would increase. And if m were to be decreased, the cooling rate would decrease. Strictly speaking, it should be the mass flowrate and not the mass that would be the parameter.
How do temperature and pressure affect the rates of mass transfer in gassesliquids and solids?
the rate of mass thrnsfer can be affected higher in gases, slower in liquid and it is not affected in solid
What does an insulator do to the rate of heat transfer?
It reduces the rate of transfer.
What is mass transfer?
Mass transfer is the net movement of mass from one location to another
What is the transfer rate of FPM-Ram?
The transfer rate of Fpm is 320MBps.
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 actual speed of data transfer on a network?
less than the data transfer rate
How do you find a file size if you have the transfer rate and transfer time?
File size = transfer rate x transfer timeThe time unit of the transfer rate and the transfer time must be the same measurement - that is, if the rate is some KB per second, then the transfer time must be in the unit of second as well
How do you find the transfer time if you have the transfer rate and file size?
File size = transfer rate x transfer timeThe time unit of the transfer rate and the transfer time must be the same measurement - that is, if the rate is some KB per second, then the transfer time must be in the unit of second as well
What has the author J A Goodhead written?
J A. Goodhead has written: 'Drop size distribution and mass transfer rate in a Graesser contractor'
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
Furious lows of mass transfer?
The Furious laws of mass transfer is the net movement of mass from one location to another.
