Pleural effusion

. Definition:A pleural effusion is an excessive accumulation of fluid in the pleural space. It can be detected on X-ray when 300 mL or more of fluid is present and clinically when 500 mL or more is present. The chest X-ray appearances range from the obliteration of the costophrenic angle to dense

Diffusion and Effusion

Diffusion and Effusion

Diffusion and Effusion. The rates of diffusion and effusion depend on the relative velocities of the gas molecules. The faster the gas molecules are moving, the faster they diffuse/effuse. At the same temperature, molecules with a lower mass move faster than molecules with a higher mass.
