Question

state the conditions under which newton's law of cooling is applicable

Answer 1

HLO MATE HERE IS UR ANSWER.

❤. NEWTONŚ LAW OF COOLING IS APPLICABLE ❤

• When
• Heat is lost by the body is mainly due to convection.
• Loss of jeat is negligible by conduction.
• The hot body is cooled by forced convection.
• The temperature of every part of the body is same.

Answer 2

Conditions under which Newton's law of cooling is applicable;

• Heat loss due to convection is only allowed.
• Even if there is heat loss by conduction, it has to be negligible.
• The heat loss has to be in a streamlined flow of air and this is called forced convection.
• The temperature distribution has to be even along the entire body.
• The difference in temperatures should be moderate.
• In the case of forced convection, some level of large temperature difference is allowed.
