Really Keepit.I am trying to keep this forum on track and you stir the pot.I read a book on pilots dated back a while and the new pilot was landing a plane at night then all of a sudden the senior pilot started lighting matches in the cabin as at the end the senior explained It is not always going to be good conditions.I have no trouble with ITN flying airplanes

How to Convert Joules to Kelvin

Updated March 13, 2018 By Michael Judge.

Example...

If 4,000 joules of energy were provided to 500 g of water, you would calculate 4,000/500 = 8.

Divide the result of the previous calculation by the specific heat capacity of the substance. You can generally obtain the specific heat capacity of a chemical substance from the manufacturer's literature or from a scientific reference source such as the CRC Handbook of Chemistry and Physics. The result of this calculation is the temperature increase of the substance, in units of degrees Celsius. The specific heat capacity of water is g/4.19 J - degrees Celsius. In the example the calculation would be 8/4.19 = 1.9 degrees Celsius.

Add the temperature increase just derived to the substance. This gives you the temperature after the heat input. If the water in the example had initially been at 25 degrees, its temperature after heating would be 25 + 1.9 = 26.9 degrees Celsius.

Add 273.1 to the final temperature of the substance that was just calculated. This is the conversion factor to change from units of degrees Celsius to Kelvin (K). The result is the temperature of the material after the heat input in kelvins. The water temperature would be 26.9 + 273.1 = 300 K.

1. That will not tell you the temperature. It will tell you how much temperature will increase or decrease. If you don't know the starting temperature then you won't know the ending temperature.

2. All of the above is material dependent, i.e. you need an additional parameter, you need the specific heat.

Heh. Any passengers I have tend to sleep during long flights. They don't feel uptight with my flying at all. Indeed, most enjoy the fantastic view you get in small aircraft. I still do, though I've flown for most of my life.

I can sock the ole' needles home without bouncing all over the sky like a lot of pilots do, and keep 'em there all the down to the threshold.

We do have one airport in the area with a most unusual approach system, not commonly seen, called a PAR approach. Under this system, a radar operator is giving you azimuth and glide slope information. He literally talks you through the approach. The only onboard equipment required is a single COM radio. The runway to this airport is tiny. It looks like someone carved a bike path in the middle of a farm. It's not much wider than the wheels on the aircraft.

About the most interesting approach I had was when I lost the attitude gyro while I was on the approach. Epic failure for the instrument too. Instead of just tipping over and dying, like usual, the card snagged on the gyro axis and started spinning rapidly. I completed the approach normally since I was already established. I really didn't need the gyro then. Yes...I was still in instrument conditions when it happened.

A quick replacement of the instrument and the plane was back in service. I still have that dead gyro, just to show people. The card still spins when the gyro spins. For gyro failures, that one's a classic.

This is not converting joules to degrees kelvin. You just built a calorimeter. which doesn't measure temperature.

Howard Air Force Base in Panamá used PAR. The base also installed an ILS in the late 90s that put the PAR in second chair until an F-16 pilot backed right up to the ILS localizer array and hit the afterburners ... and the PAR returned to primary use until the ILS was repaired.

Ouch! I bet someone caught hell for that one!
How much did it melt before it was blown off it's mounts? Do you know, or have pictures of it?

You might have missed that little detail that it was an F-16 pilot. They don't get in trouble unless there is loss of life or aircraft. The 24th Communications Squadron Commander was instead chastized for placing the array too close to where the fighter pilot needed to take off.

Into the Night wrote:How much did it melt before it was blown off it's mounts?

It was totally destroyed. Fortunately, the 24th Wing had the budget to acquire a new one and some airmen got a first-rate opportunity to get certified in installing the array (which differs from being certified to maintain the array).

Sorry, I have no photos.

We have good knowledge of the specific heat of air in our atmosphere, in Joule per Kelvin and Kilogram. And good knowledge of the mass of air in an area.

If the Sun stops shining, how long before temperatures reach zero Kelvin?

Assume the starting temperature of Earth is zero Kelvin before Joules are added. There you go. The example is applicable.

It won't ever happen.

Are you trying to argue that joules applied to the atmosphere will increase its temperature in such a way that it will never cool? I'm not following this rabbit hole.

I certainly don't blame the F-16 pilot. I would blame the Squadron Commander as well. That was really a twit move to install a thing like that so close to the runway threshold.

Wish there were some photos of it. It must've been a mess!
