What is heat balance?
Definition of heat balance : the distribution of the heat energy supplied to a thermomechanical system (as a steam power plant) among the various drains upon it including both useful output and losses also : an evaluation or record of such distribution.
What is heat production?
Heat production is a side product of metabolic processes, the continuous occurrence of which provides the energy basis of life. This heat production necessarily increases the temperature of an organism above that of the environment.
What is heat dissipation mechanism?
Heat loss occurs through four mechanisms: evaporation, convection, conduction, and radiation.
What is heat dissipation rate?
Heat dissipation represents a form of energy dissipation (energy transfer). Energy dissipation is a measure of energy lost due to temperature difference and inefficiencies. Conduction, which allows heat to dissipate throughout a material and possibly into a different material that is in contact with the hot material.
What is the balance between heat produced?
Heat balance (thermal equilibrium) is the balance between the rate of heat production and the rate of heat loss.
What is heat balance Wikipedia?
(geophysics) The equilibrium which exists on the average between the radiation received by the earth and atmosphere from the sun and that emitted by the earth and atmosphere.
Why is heat produced during exercise?
Body heat is increased with exercise because your body is being active, your heart rate is increasing, and the result is your body will sweat which is our way of cooling ourselves down. As your body absorbs the sweat we produce it will result in releasing heat.
What is dissipative process?
In a dissipative process, energy (internal, bulk flow kinetic, or system potential) transforms from an initial form to a final form, where the capacity of the final form to do mechanical work is less than that of the initial form.
What causes dissipation?
Dissipation is a term that is often used to describe ways in which energy is wasted. In a mechanical system, energy is dissipated when two surfaces rub together. Work is done against friction which causes heating of the two surfaces – so the internal (thermal) energy of the surfaces increases.
What is heat dissipation formula?
To determine how much heat a fluid loses (or gains) through a system, we can use the following equation: Q = m C_p \Delta T \tag{1} Where Q (W) is the heat that the fluid loses/gains, m (\frac{kg}{s}) is the mass flow rate of the fluid, C_p (\frac{J}{kg.
What does good heat dissipation mean?
1. heat dissipation – dissipation of heat. chilling, cooling, temperature reduction – the process of becoming cooler; a falling temperature. Based on WordNet 3.0, Farlex clipart collection.
What is the relationship between heat dissipation and metabolism?
Therefore, it’s an increase in metabolism during muscular activity that produces additional heat. Under these conditions, metabolic heat production may increase to an extent that heat production is greater than heat dissipation; thus, the body will store heat and body temperature will increase, a condition known as hyperthermia.
What is the relationship between heat production and body temperature?
Under these conditions, metabolic heat production may increase to an extent that heat production is greater than heat dissipation; thus, the body will store heat and body temperature will increase, a condition known as hyperthermia. This heat must be dissipated to prevent a dangerous increase in core temperature.
How much heat does the human body produce and dissipate?
Our metabolic heat production (which can vary between 70W at sleep and 700 W at very heavy work or vigorous sport) must be dissipated, thus the heat flow is always away from the body. This equilibrium is a dynamic one: the uncontrollable change of one factor can be compensated for by an inverse change of another – within limits.
What happens when the body’s temperature is out of balance?
When out of balance, the body either gains or loses heat. The temperature control center, which is located in the hypothalamus, works like a thermostat. It can initiate an increase in heat production when body temperature falls.
