Isentropic Compression Equations FAQ

What is meant by isentropic compression process?

Isentropic (or adiabatic) Compression/Expansion Processes. If compression or expansion of gas takes place with no flow of heat energy either into or out of the gas - the process is said to be isentropic or adiabatic. The isentropic (adiabatic) process can be expressed with the Ideal Gas Law as. p / ρk = constant (2) where.

What is the formula for the isentropic process?

The isentropic process (a special case of adiabatic process) can be expressed with the ideal gas law as: pV κ = constant. or. p 1 V 1 κ = p 2 V 2 κ. in which κ = c p /c v is the ratio of the specific heats (or heat capacities) for the gas. One for constant pressure (c p) and one for constant volume (c v).

How do you find the temperature of an isentropic compression?

For an isentropic compression, the discharge temperature is determined by the pressure ratio as: (14.8)T2 T1 = (p2 p1)k − 1 k where k (isentropic exponent) is ratio of the heat capacities of gas at constant pressure and temperature (k = C p /C v), p 1 is suction pressure, and p2 is discharge pressure.

What are isothermal and isentropic gas compression and expansion processes?

Isothermal and isentropic gas compression and expansion processes. The relationship between pressure and density when compressing - or expanding - a gas depends on the nature of the process. The process can be If compression or expansion of gas takes place under constant temperature conditions - the process is said to be isothermal.
