Question of the Week / Re: QotW - 11.05.29 - At what speed does windchill give way to frictional heating?
« on: 20/12/2011 12:47:38 »
May I add an alternative to racing down the highway at 200km/h in a cabrio, naked and covered in vaseline, ie. Get a scuba tank(fulll) and attach a hose to the valve. Hold the hose opening close to your forearm, and open the valve slowly. Stop when the skin starts peeling off.
Should you feel heat at any moment during the experiment, measure the airspeed through the hose with a wind meter. Ok this idea is possibly not all that accurate, but it may give you an idea on which you can deviate.
