Isentropic relations are important for analyzing the flow of compressible fluids, such as gases, in scenarios without heat transfer or friction. They help predict how pressure, temperature, and density change in a flowing fluid.
Here are some key points about isentropic relations:
Definition
The term “isentropic” comes from the Greek words isos meaning equal and entropia meaning entropy.
Idealization
An isentropic process is an idealization of an actual method. In real-world applications, total isolation of a system is not possible, so the isentropic process is an approximation.
Examples
Pumps, turbines, nozzles, gas compressors, and diffusers are examples of devices that can be analyzed using isentropic relations.
Mach number
The Mach number plays an important role in isentropic relations. If the Mach number of the flow is determined, all the other flow relations can be determined.The equation for power isP=W/tcap P equals cap W / t

Power is the rate at which energy is transferred or converted, or the rate at which work is done.In the metric system, the unit of power is the watt, which is equal to one joule per second.In the English system, the unit of power is the horsepower (hp), which is equal to 550 foot-pounds per second.
