Worked Example: CSIR NET Solved Question on Transport of Gases For CSIR NET
A gas enters the alveoli of the lungs at a rate of 10 mL/s. If the alveolar volume is 150 mL, what is the rate of diffusion of the gas, and how does it relate to gas transport?
To solve this problem, rate of diffusion is defined as the rate at which a gas moves across a unit area, typically measured in units of volume per unit time per unit area, a concept that is crucial for Transport of gases For CSIR NET. However, in this context, understanding the relationship between the rate of gas entry and alveolar volume is crucial for gas transport.
The rate of diffusion of the gas can be estimated using Fick’s laws of diffusion, which is relevant to Transport of gases For CSIR NET. However, the question seems to guide towards a simpler relationship, one that is often tested in gas transport. Given that:
- Rate of gas entry = 10 mL/s
- Alveolar volume = 150 mL
The question seems to actually aim at understanding the concept of turnover rate or how quickly the alveolar volume is replaced, a concept related to gas transport. This can be calculated as:
Rate of diffusion or turnover rate = Rate of gas entry / Alveolar volume = 10 mL/s / 150 mL
Calculating this gives:
Rate of diffusion = 10 / 150 s-1= 1/15 s-1= 0.0667 s-1, which is an important calculation for gas transport.
