WebSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass. WebIn general, the literature on heat transfer referred to as Peclet-number, the thermal number describes the relation of convective heat transport by mass flow (h · v c) and diffusive heat transport (a −1). In their investigations, Chao and Trigger varied the thermal number solely through the cutting velocity and the depth of cut, as they ...
