Detailed explanation-1: -The energy flux (TRANSP) due to transpiration may now be found: TRAN SP = flux i+flux 2+flux 3-flux 4+flux 5.
Detailed explanation-2: -Under normal circumstances, the rate of water uptake gives a measure of the rate of transpiration. A simple potometer is a piece of capillary tubing to which a plant has been connected. The water uptake is measured by recording the time taken for a bubble in the tube to move a set distance.
Detailed explanation-3: -A potometer is a device, which is used to measure water uptake by the plant shoot during transpiration. It is also known as transpirometer. Ganong’s potometer is used to measure the transpiration rate in a laboratory.
Detailed explanation-4: -In SI notation transpiration may be expressed as milligrams H2O per meter squared per second
