Instruction

  1. Start the clock. Measure the wet-bulb temperature (TW) by Assman Psychrometer. The level rises above 38°C mark.
  2. The Kata-thermometer is placed in front of the duct. After few seconds, the alcohol will drop down from 38°C to 35°C. Note the time using stopwatch.
  3. Stop the clock. And note the time.
  4. Air velocity is given by vane anemometer. Click the "Calculate" button to calculate Wet Kata Cooling Power.
  5. After that add the result to the observation table by clicking the button "Add result to observation table".
  6. Repeat the from setp 2 with different flow control devices.
  7. Plot the graph between Kata cooling power and air velocity by click "Plot Graph" and To find the best fit line click " Best Fit Graph".
