# Análisis 59: Enfriamiento evaporativo en ciclo de turbina de gas

{% hint style="info" %}
Una mezcla de hidrocarburos se emplea como combustible en un ciclo de Brayton no regenerativo. El aire entra con un 190 % en exceso. Las condiciones ambientales son 25 ºC y 100 kPa y es mezclado con el combustible que entra en las mismas condiciones, antes de la combustión. La temperatura alcanzada por los gases de combustión es de 1200 ºC y la cámara de combustión trabaja a 1000 kPa, sin pérdida de carga. Las eficiencias isoentrópicas de ambas turbomáquinas son del 89 %. La presión en el escape es de 100 kPa.

* n-C<sub>8</sub>H<sub>18</sub> -> 84 %
* C<sub>5</sub>H<sub>8</sub>O -->  10 %
* C<sub>4</sub>H<sub>8</sub>O -->  6%

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://thermosuite.gitbook.io/thermocombustion-hf/analisis-51-al-60/analisis-59-enfriamiento-evaporativo-en-ciclo-de-turbina-de-gas.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
