Water pressure, volume, temperature

Click For Summary
SUMMARY

The discussion focuses on determining the relationship between water pressure, volume, and temperature, specifically in the context of testing an aerosol canister's pressure tolerance. The user seeks accurate data for water pressures at constant volume, particularly at boiling point (100°C), where the pressure is established at 1 atm. The user also notes that in a closed system, pressure increases according to the standard saturated liquid water table. This information is crucial for understanding the behavior of water under heat in a sealed environment.

PREREQUISITES
  • Understanding of thermodynamics principles, particularly related to pressure and temperature.
  • Familiarity with the concept of saturated liquid water and its pressure-temperature relationship.
  • Knowledge of heat transfer and heat capacity calculations.
  • Experience with experimental setups involving pressure testing of sealed containers.
NEXT STEPS
  • Research the standard saturated liquid water table for accurate pressure values at various temperatures.
  • Learn about the ideal gas law and its application in closed systems.
  • Investigate methods for measuring pressure in sealed containers during thermal experiments.
  • Explore safety protocols for conducting high-pressure tests with aerosol canisters.
USEFUL FOR

Engineers, physicists, and hobbyists involved in experimental thermodynamics, particularly those testing pressure limits in sealed systems or working with aerosol canisters.

Hi There

Can some one please help me find a table or chart that has accurate data for water pressures and temperatures at constant volume. I'm testing how much pressure an aerosole canister can take by filling it with water, sealing it and applying a flame tourch. I know how much heat the trouch is putting out, so I'm timing how long it'll take for the can to blow out. From this and the heat capacity I can get the temperature of the water, but now I'm having serious difficulty finding the pressure of the water given the temperature and volume. Any help please?

It has just dawned upon me that, in fact, the pressure of the water at boiling point (100C) is 1 atm. Hence if it is a closed system, that pressure will increase according to the standard saturated liquid water table. Thanks a lot.
