A Heat Exchanger is a device which is used to transfer heat from one medium to other. A common example is the radiator in an automobile, which transfers the heat from the liquid engine coolant to the air pulled through the radiator by the fan.
What else can I help you with?
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.
What is an adiabatic process and how is it defined as one in which there is no heat exchange with the surroundings?
An adiabatic process is when there is no heat exchange with the surroundings. This means that no heat is added or removed from the system during the process.
How is countercurrent exchange important in heat exchange?
Countercurrent exchange maximizes heat transfer between two fluid streams by maintaining a steep concentration gradient throughout the exchange process, resulting in more efficient heat transfer. This mechanism allows organisms to conserve energy by reclaiming heat from outgoing fluids and transferring it to incoming fluids. It is commonly seen in biological systems like fish gills and mammalian kidneys to optimize heat exchange and maintain homeostasis.
How does a stirling engine work?
It has heat exchange.
What is radiative exchange?
Radiative exchange refers to the transfer of heat through electromagnetic radiation between two surfaces at different temperatures. This process can occur in a vacuum and does not require a medium for heat transfer. The rate of radiative exchange is dependent on the temperature and emissivity of the surfaces involved.
What is an example of heat exchange?
An example of heat exchange is when a warm cup of coffee transfers heat to a cooler room, causing the coffee to cool down over time. This is known as convection, where warmer substances transfer heat to cooler substances through contact.
What is the low of heat exchange?
The law of heat exchange, also known as the second law of thermodynamics, states that heat will naturally flow from a higher temperature to a lower temperature until equilibrium is reached. This principle governs the direction in which heat is transferred between objects and systems.
What mode of heat exchange is involved in wind chill?
Convection
Closed systems exchange energy but do not exchange?
Closed systems exchange energy with their surroundings in the form of heat or work, but do not exchange matter. This means that the total amount of mass in a closed system remains constant over time. Examples of closed systems include sealed containers and insulated thermos flasks.
Heat exchange in chemical reactions is due to a change in what?
Enthalpy-The heat added to or loss by a system at constant pressure
What is mean by agitated vessel heat exchanger?
Agitated vessel heat exchange refers to the heat exchange that is carried by the internal coils or through the external jacket on the vessel. A recirculation loop with an external heat exchanger may be used when the coils or jacket cannot provide the surface area required.
What process takes place at the capillaries?
gases exchange .to release heat.
