What governs the amount of heat dissipation over the heated surface?
The amount of heat dissipation over a heated surface is primarily governed by factors such as the temperature difference between the surface and its surroundings, the thermal conductivity of the material, the surface area, and the presence of any insulation or cooling mechanisms. Heat dissipation increases with a higher temperature difference and greater surface area, and decreases with higher thermal conductivity and effective insulation.
What is the difference between precipitation and condensation.?
The difference between condensation and precipitation is that condensation is the transformation of state from a gas to a liqiud and precipitation is next stage after condensation where waterdroplets become larger and larger so as they fall under gravity in form of rain from the cloud.
What is the difference between precipitation and ground water?
Precipitation is rain (or snow etc) falling from the clouds. When it lands it becomes surface water in rivers, lakes and oceans. If it seeps into the earth it becomes groundwater, usually in aquifers.
What is Rate of fall of temperature of the body is directly proportional to?
The rate of fall of temperature of the body is directly proportional to the temperature difference between the body and its surroundings, the surface area of the body exposed, and the thermal conductivity of the material between the body and its surroundings.
What four ways can you increase the rate of heat transfer?
Increase the temperature difference between the objects. Increase the surface area of contact between the objects. Improve the thermal conductivity of the material. Increase the flow rate of a fluid (in the case of convection).
What is heat loss formulae of water flow through PPR-C pipe line?
you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) =Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)
What is the meaning of thermal conductivity?
It is the ability of substance to conduct heat. In mathematics thermal conductivity is the heat energy transferred per unit time and per unit surface area divided by temperature difference.
What is the relationship between evaporation and precipitation?
Evaporation is the process where water changes from liquid to vapor, typically from the Earth's surface into the atmosphere. Precipitation is when water vapor in the atmosphere condenses and falls back to the Earth's surface in the form of rain, snow, sleet, or hail. Together, evaporation and precipitation are part of the water cycle, where water is continuously circulated between the Earth's surface and the atmosphere.
What is the Difference between the surface and subsurface?
The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water
The difference between computer and surface computer?
the computer is the device. the computer surface is the surface it sits on
What is the difference between apparent surface area and accepted surface area?
manila
What determines the flow of heat between two objects in contact?
The flow of heat between two objects in contact is determined by the temperature difference between the two objects, the thermal conductivity of the materials involved, and the surface area of contact. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.
