SUMMARY

This discussion focuses on the use of thermodynamic tables for water (H2O) to complete a specific data table involving temperature, pressure, enthalpy, and phase description. Key insights include the necessity of identifying two intensive properties to begin the analysis and the importance of selecting the appropriate tables: saturated tables for phase data, compressed liquid tables for high pressures, and superheated vapor tables for high temperatures. Additionally, interpolation is required when exact values are not available in the tables.

PREREQUISITES
  • Understanding of thermodynamic properties, specifically intensive properties.
  • Familiarity with thermodynamic tables for water (H2O).
  • Knowledge of interpolation techniques for data estimation.
  • Basic concepts of phases of matter (liquid, vapor, saturated).
NEXT STEPS
  • Study the structure and use of thermodynamic tables for water (H2O).
  • Learn about interpolation methods for estimating values in thermodynamic data.
  • Explore the differences between saturated, compressed liquid, and superheated vapor tables.
  • Practice solving thermodynamic problems involving enthalpy and phase transitions.
USEFUL FOR

Students in thermodynamics courses, engineers working with heat transfer and fluid mechanics, and anyone needing to understand the application of thermodynamic tables for water (H2O).

Homework Statement



Complete this table for H20:

Homework Equations



T, °C...P, kPa.....h, kJ/kg...x Phase...description
200 ............0.7
140.........1800
......95.........0.0
80....500
......800.....3162.2I just need help getting started, all I have is a packet full of tables and I don't know which to use and when, if someone could give me some general information on solving this type of questions so I can do other ones by myself it would be much appreciated.

I know that were supposed to find 2 intensive properties to start but then I don't know what to do since there a lot of tables. Does anyone know how to do this?
 
You just have to match up the values. If you have a phase it will be in the saturated tables, high pressures in compressed liquid tables, and high temperatures in superheated vapor tables. If you can't find the numbers on the tables then you have to use interpolation.
