The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is radiation the transfer of heat by the movement of a fluid?
No, most forms of radiation have nothing to do with heat. Transfer of heat by the movement of a fluid is called convection.
A convection current transfers heat or air within a fluid?
a convection current transfers heat within a fluid.
When the heat source is removed from a fluid convection occurring in the fluid will do what?
Eventually stop
What is the Formula for calculating heat transfer by convection?
heat rate = characteristic of fluid and structures * area * difference in temperature between surface and bulk fluid
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Is radiation the transfer of heat by the movement of a fluid?
No, most forms of radiation have nothing to do with heat. Transfer of heat by the movement of a fluid is called convection.
What is heat duty?
heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
A convection current transfers heat or air within a fluid?
a convection current transfers heat within a fluid.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What method of heat represents the transfer of heat in a fluid?
Convection
What is Efficiency of shell and tube heat exchanger?
A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.A slightly different definition of efficiency applies to cooling:Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.
What happens to the density of a fluid when heat is applied?
The density of a fluid goes down (becomes less dense) when heat is applied.
What heat transfer can travel through a fluid?
Heat can transfer through a fluid by conduction and/or convection (with convection being the most efficient). If the fluid is a gas then heat can also transfer through it by radiation (but this does not work in liquid fluids).
What is the transfer of heat in a fluid?
convection
Which fluid is introduced first in heat exchange?
Since the question is about heat exchange, I assume it is a man made. The first form of heat exchange is cooking. The first fluid is then water.
