numerical: transpiration rate

Question

A plant transpires 27 mL of water over 6 hours through 3 leaves equally. What is the average transpiration per leaf per hour? (mL h^-1)

1. **Total Rate**: Calculate the total amount of water transpired by the entire plant per hour.
   - $Total \ Hourly \ Rate = \frac{Total \ Water}{Total \ Time} = \frac{27 \ ml}{6 \ hours} = 4.5 \ ml/hour$.
2. **Per Leaf Rate**: Since the water is lost through 3 leaves equally, divide the total hourly rate by the number of leaves.
   - $Rate \ per \ leaf = \frac{4.5 \ ml/hour}{3 \ leaves} = \mathbf{1.5 \ ml/h^{-1}}$.
3. **Conclusion**: On average, each leaf loses $1.5 \ ml$ of water every hour.
