What is the physical significance of nusselt number how is it related with convection and conduction heat transfer hence work out its relationship with the appropriate prameters?
The Nusselt number is the ratio of convective to conductive heat transfer across the boundary layer. Nu=(hL)/k h is heat transfer coefficient L is the characteristic length k is the thermal conductivity
Which layer the sun moves heat energy to the convective layer?
radiative layer
What is radiation heat?
Radiate heat is ENERGY TRANSFER at a distance FROM ONE OBJECT to ANOTHER OBJECT through a form of 1. heat conduction through a medium. 2. heat waves (a variety of light waves) in the Infrared region of light 3. Energy transfer with a transfer agent. The object that heat is being radiated TO (the target), then rises in temperature, due to the transfer of energy.
How does the suns core transfers heats to the surface?
In part through convection, but most regions of the Sun or non-convective; as a result, heat transfer is mainly by radiation: a photon gets absorbed by an atom, then it gets re-emitted soon.
When a metal pan is heated on the stove what is it?
All stove flames are hotter than you would expect any pan to normally be so there is a temperature gradient between the flame and the pan. Heat is transferred from the hot gasses of the flame to the pan by two mechanisms: convective heat transfer and radiant heat transfer. Note that the hotter the flame, the more significant the radiant heat transfer becomes.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How many heat transfer zone in boiler?
convective and radiant heat transfer
Which point indicates convective heat transfer?
W
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
The heat from a campfire is transferred by what energy?
Radiant heat transfer is the primary way you feel heat from a campfire. There would also be convective and conductive heat transfer to the air.
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.
What is the convective heat transfer coefficinet for air at atmospheric condition and how it change with other factors?
The convective heat transfer of any fluid is dependent on its velocity, viscosity...and other properties. The higher the velocity the higher the coefficient. Generally indoor convective heat transfer of air is approximately 40 W/m2.K It varys depending on wind conditions, generally within the range of 10-100 W/m2.K

How is the transfer of energy in a pan of hot water similar to the transfer of energy in the sun convective Zone?
In both cases, heat is transferred via convection.

Is convection a way heat ia transported?
yes convection is way of heat transfer. example : in boilers evaporators are heated up with exhaust gases of coal burning., smoking cigareetes have convective heat transfer to mouth.
