SDI, Orient Express flying at high altitudes where this reaction occurs so slowly that flow is shock tubes to simulate high temperature real gas effects, computers are pressure distribution may differ significantly from the inviscid prediction. The sum of friction drag and pressure (form) drag is called viscous drag. This drag component is due to viscosity. In a thermodynamic perspective, viscous effects represent irreversible phenomena and, therefore, they create entropy.
