The heat capacity rate is heat transfer terminology used in thermodynamics and different forms of engineering denoting the quantity of heat a flowing fluid of a certain mass flow rate is able to absorb or release per unit temperature change per unit time. It is typically denoted as C, listed from empirical data experimentally determined in various reference works, and is typically stated as a comparison between a hot and a cold fluid, Ch and Cc either graphically, or as a linearized equation. It is an important quantity in heat exchanger technology common to either heating or cooling systems and needs, and the solution of many real world problems such as the design of disparate items as different as a microprocessor and an internal combustion engine.

... A hot fluid's heat capacity rate can be much greater than, equal to, or much less than the heat capacity rate of the same fluid when cold ... In practice, it is most important in specifying heat-exchanger systems, wherein one fluid usually of dissimilar nature is used to cool another fluid such as the hot gases or steam cooled in a power plant by a heat ... As the ability of a fluid to resist change in temperature itself changes as heat transfer occurs changing its net average instantaneous temperature, it is a quantity of interest in designs which have ...
Famous quotes containing the words rate, heat and/or capacity:
“Terence, this is stupid stuff:
You eat your victuals fast enough;
There cant be much amiss, tis clear,
To see the rate you drink your beer.”
—A.E. (Alfred Edward)
“Even if you find yourself in a heated exchange with your toddler, it is better for your child to feel the heat rather than for him to feel you withdraw emotionally.... Active and emotional involvement between parent and child helps the child make the limits a part of himself.”
—Stanley I. Greenspan (20th century)
“That way of life against which my generation rebelled had given us grim courage, fortitude, self-discipline, a sense of individual responsibility, and a capacity for relentless hard work.”
