SUMMARY

The discussion centers on the pressure equilibrium in two connected gas cylinders with initial pressures of 1.5 bar and 0.5 bar. When connected, the final pressure in both cylinders will equalize to 1.0 bar, assuming they have the same capacity and the temperature remains constant. If the cylinders have different diameters, the final pressure calculation will require additional considerations regarding their volumes. The principles of gas laws and pressure equilibrium are essential to understanding this scenario.

PREREQUISITES
  • Understanding of gas laws, particularly Boyle's Law
  • Knowledge of pressure measurement units, specifically bar
  • Familiarity with concepts of pressure equilibrium
  • Basic principles of thermodynamics related to gas behavior
NEXT STEPS
  • Research Boyle's Law and its applications in gas pressure calculations
  • Learn about pressure measurement and conversion between units
  • Explore the effects of temperature on gas pressure and volume
  • Investigate the implications of varying cylinder volumes on pressure equilibrium
USEFUL FOR

Students studying physics, engineers working with gas systems, and anyone interested in thermodynamics and fluid mechanics will benefit from this discussion.

Hi

Suppose there are two cylinders / vessels.
In one cylinder the pressure is 1.5 bar & in other 0.5 bar.If both cylinder are connected internally through valve connection, what will be the final pressure in both? explain
 
Physics news on Phys.org
You did not mention if the two cylinders are of the same capacity. If so, the pressure is 1.0 bar in both provided that the temperature is unchanged.
 
Let the two cyclinders have different diameters, D and d
