The datum location of a Cessna 172F is typically located at the leading edge of the wing, specifically at the wing's root. This reference point is used for weight and balance calculations to ensure the aircraft is within its center of gravity limits for safe operation. Properly identifying and utilizing the datum is crucial for maintaining the aircraft's performance and stability during flight.
Upon Review of the question: THIS ANSWER IS FOR THERMOSTAT TEMPERATURES, NOT AVERAGE RUNNING TEMPERATURE, IF THEY ARE ANY DIFFERENT. 1990s 5th Generation Accords: Open 169-176. Full open: 194. Therefore I believe that the 180-degree thermostats are what you want, but I'm not sure if the stamped-on temperature is opening temperature or running temperature?? 180F ~=83Celcius, so get close to that. 78C = 172F, about the opening temperature.
To distill alcohol from any fermented drink or liquid such as wine, moonshine corn mash or fermented molasses, you need to get the temperature of that said liquid up to 78C (172F) and keep it below the boiling temperature of water 100C (212F) so then you boil off the alcohol and leave the water and other stuff behind. You have to capture the alcohol vapors and cool it down so it can be a drinkable liquid. What is normally done is copper tubing wrapped in a coil or corkscrew shape and submerged in cold water. The liquid coming out of your "still" should be alcohol, but you MUST throw away the first part of it I'm not sure of the exact measurement) because it will be Methanol a very toxic form of alcohol that will make you blind. In most places it is illegal to distill your own alcohol, so if you are stupid enough to try this with out the proper knowledge, find out what your local laws are so then you don't get into any legal trouble.
