Methods to Apply Newton’s Law of Cooling
At a constant rate of cooling, the rate of cooling is related to the average temperature of the body during the interval then we can calculate the approximate value, using Newton’s Law of Cooling
dθ/dt = k(q – qs)
where,
q is the temperature of the body
qs is the temperature of the surrounding
Now if the average temperature of the body is q, where,
q = (qi + qf)/2
Newton’s Law of Cooling
Newton’s Law of Cooling is the fundamental law that describes the rate of heat transfer by a body to its surrounding through radiation. This law state that the rate at which the body radiate heats is directly proportional to the difference in the temperature of the body from its surrounding, given that the difference in temperature is low. i.e. the higher the difference between the temperature of the body and its surrounding the more heat is lost and the lower the temperature the less heat is lost. Newton’s Law of Cooling is a special case of Stefan-Boltzmann’s Law.
In this article, we will learn about, Newton’s Law of Cooling, Newton’s Law of Cooling Formula, its Derivation, Examples, and others in detail.
