In a lab experiment measuring dibenzofuran flux, the soil's moisture is 20%, and the partition constant is adjusted. If the moisture drops to 10%, calculate the expected change in flux assuming a linear relationship.
💡 Hint: Consider how the partition constant effects scaling with moisture.
A researcher measures airflow velocity at two heights above the ground. If at height 1 (z1), the velocity is 2 m/s and at height 2 (z2), it is 4 m/s, calculate the friction velocity (v*) assuming no other forces are acting.
💡 Hint: Remember to refer to tje equation concerning surfaces for better accuracy.
