9.2.7.1 Basic Definitions Critical temperature (T c)The maximum temperature at which a gas can be converted into a liquid by an increase inpressure. Critical pressure (p c)The minimum pressure which would suffice to liquefy a substance at its criticaltemperature. Above the critical pressure, increasing the temperature will not cause a fluidto vaporize to give a two-phase system.
Critical depth is a quantity of fundamental importance to understanding the flow characteristics. If the actual depth is greater than critical depth, then the flow is considered subcritical. Subcritical flow is slow flow and is impacted by downstream conditions. If the actual depth is less than critical depth, then the flow is supercritical. Supercritical flow is fast flow and is impacted by upstream conditions.
