It is the rate at which heat loss occurs from the surface of an object. It is either expressed in J/KJ/time unit or in deg C/time unit. cooling rate is an indicator to achieve desired mechanical properties such as hardness, conditions such stress-relieved etc.

What the definition of critical cooling rate in a context of austenite transformation?
The slowest rate of cooling from the hardening temperature which will produce the fully hardened martensitic condition.
What are the effects of heat input and the effects of the rate of cooling and heat distribution during welding on the grain structure of two given welded joints?
If you have no idea - don't write anything..
What is range in cooling tower?
Range is the difference of cooling water inlet and cooling water outlet temp
What is difference between cooling load and heating load?
Cooling Load is the amount of energy that is to be extracted from a house to develop a conditioned environment. There are two types of cooling loads i.e, sensible cooling load and latent cooling load.... Heating Load is the amount of heat that is to be supplied to a house in order to increase its temperature to maintain desired temperature...
Why is cooling in IC engine so important?
without cooling engine block may be cracked or eroded and head gasket might be damaged early.
What is the effect of cooling on pulse rate?
Cooling slows heart rate, thus slowing the pulse rate.
Why do some types of batteries stays fresh longer if they are kept in a refrigerator?
Cooling lowers the rate of the chemical reaction in the batteries.
What are three things crystal size dependent on?
Primarily the cooling rate of the mineral compound.The faster the rate cooling smaller the crystal size of the mineral.Consequently, large crystal specimins are derived from igneous bodies with a very slow rate of cooling.
How does the speed of cooling of molten rock affect the size of crystals that form?
fast cooling rate forms smaller crystals eg Andesiteslow cooling rate forms large crystals eg.Pegmatite
What is the rate of cooling for gabbro?
it doesn't cool
What is recirculation rate of cooling tower?
aaa
What the definition of critical cooling rate in a context of austenite transformation?
The slowest rate of cooling from the hardening temperature which will produce the fully hardened martensitic condition.
How do you calculate rate of cooling if you are given temp of 88.9 and a volume of 150 ml and time of 4 seconds?
There is not enough information to calculate the rate of cooling.
What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.
Is igneous rock that formed from cooling lava fined-grained?
yes because of the fast cooling rate
A coarse-grained rock and a fine-grained rock probably had different .?
Cooling rate
How does surface area affect the rate of cooling?
the color of an object will affect the rate of cooling e.g black objects cool down faster than shiny objects, the temperature around the object will also affect the rate of cooling, if the surrounding is cold, a hot object will cool faster than when the surrounding is hot.
