Homework Help Overview

The original poster is tasked with designing a power generating system using specific parameters involving hot air and steam streams, as well as a lake's temperature. The context is centered around thermodynamics and power generation systems.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the potential use of a Rankine cycle system, questioning how to integrate the lake water and hot air stream into the design. There are inquiries about calculating enthalpy for the steam before and after turbine entry.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the design. Some guidance has been offered regarding the Rankine cycle, but there is no clear consensus on the integration of all components or the calculations involved.

Contextual Notes

The original poster notes difficulty in finding relevant information in their study materials, which may impact their ability to fully engage with the problem.

TL;DR Summary: I've been asked to design a power generating system. I could really use some help on how to approach this question, as I cant really find something like that in my study meterial.

So I've been asked to design a system that would produce the biggest amount of power possible, using these parameters:

A Hot air stream, with a temperature of 700C, preasure of 8 Bar and a flow rate of 10 KG/min.
A stream of hot steam, with a temperature of 350C, preasure of 1 BAR, and a flow rate of 10KG/min.
A lake with a static temperature of 16C, and the air around the system which is at 22C and 1 Bar.

Any suggestions on how to approach this?

I was thinking of making a Rankine cycle system, since i'm supplied with a source of steam. The thing is, i'm not sure how to incorporate the water of the lake or the hot air stream into it. Also, while finding the Enthalpy for the steam before entering a turbine is easy enough, i'm not sure how to find the Enthalpy once it exits to calculate to amount of power the turbine generates.

Does your textbook / do your lecture notes have anything about steam turbines ?
