In thermal physics and thermodynamics , the heat capacity ratio , also known as the adiabatic index , the ratio of specific heats , or Laplace's coefficient , is the ratio of the heat capacity at constant pressure C P to heat capacity at constant volume C V. The suffixes P and V refer to constant-pressure and constant-volume conditions respectively. The heat capacity ratio is important for its applications in thermodynamical reversible processes , especially involving ideal gases ; the speed of sound depends on this factor. To understand this relation, consider the following thought experiment. A closed pneumatic cylinder contains air. The piston is locked. The pressure inside is equal to atmospheric pressure. This cylinder is heated to a certain target temperature. ratio of heat capacitiesNavigation menu
The following rati parameters plays a significant role for evaluating the convection heat transfer coefficient h :. In dimensionless form:. Reynold Number Re :. Critical Reynold Number: T he number used to show the boundary layer changes from laminar to turbine flow is called the critical Reynolds number.

Completely I share your opinion. In it something is also to me it seems it is very good idea. Completely with you I will agree.
Excuse for that I interfere … But this theme is very close to me. Write in PM.
