    Cycle
In summary, a Brayton Cycle is a thermodynamic cycle used to describe the operation of a gas turbine engine. It involves four processes and the calculation of enthalpy using the equation h = cp * T. The given temperatures in this cycle are used to calculate enthalpy change and an increase in temperature results in an increase in enthalpy. Finding enthalpies in a Brayton Cycle is important for analyzing performance and efficiency of the engine, as well as making improvements to its design.

When looking at a brayton cycle, how do you find enthalpies when your only given temperatures?

This is not a homework question, just reading through the textbook and cannot see where got the value from?

Thanks

specific heat * temp = enthalpy.
 

What is a Brayton Cycle?

A Brayton Cycle is a thermodynamic cycle used to describe the operation of a gas turbine engine. It consists of four processes: isentropic compression, constant pressure heat addition, isentropic expansion, and constant pressure heat rejection.

How do you calculate enthalpy in a Brayton Cycle?

To calculate enthalpy in a Brayton Cycle, you can use the equation h = cp * T, where h is enthalpy, cp is the specific heat at constant pressure, and T is the temperature.

What are the given temperatures in a Brayton Cycle?

The given temperatures in a Brayton Cycle are the inlet temperature, the compressor discharge temperature, the turbine inlet temperature, and the exhaust temperature. These temperatures are used to calculate the enthalpy change in each of the four processes.

How does temperature affect enthalpy in a Brayton Cycle?

In a Brayton Cycle, an increase in temperature will result in an increase in enthalpy. This is because as temperature increases, the molecules in the gas have more energy, which is reflected in the increase in enthalpy.

What is the purpose of finding enthalpies in a Brayton Cycle?

Finding enthalpies in a Brayton Cycle allows us to analyze the performance and efficiency of a gas turbine engine. It also helps us to understand the thermodynamic processes involved and make improvements to the design of the engine.
