They could have quoted it in tons or tonnes.
1 ton of refrigeration is equal to 4.7 hp. What time of day did they quote it?
Here is conversion and explanation for the different ways of defining capacity of A/C Units:
How many ergs is that when the air temperature outside is 256°K
The first time I loaded fuel in tons for volume (not bbl or m3) I was confused. It got worse when tons/hour was used in place of pressure.
what use is IHP?
When I asked how many BTUs the quoted HP could move the guy couldn’t tell me. I told him I wasn’t trying to remove horses so that little tidbit of information was kinda important. Eventually I looked up the conversion and also got the manufacturers specs. Later I was told that Daikin instructed them to quote in hp based on room size. No mention of R values, occupancy, windows etc., just room size, so no need for all that other superfluous information. It was a “developing” country.
Bigger numbers looks more impressive on the vessel’s spec sheet (aka the bragging sheet)
Question is if mass and force are different things why can tons(mass) be converted to ton-force just by changing the units to “ton- force”? Same with lbm and lbf.
It’s because it works if one uses standard gravity.
Newtons 2nd law: F = ma.
ɡ₀ = standard gravity
a = ɡ₀
F = mɡ₀
The actual conversion is confusing and requires getting the units correct but there’s an explanation here.
Classrooms, product development, and marketing departments.
its a bit like saying the engine is 45% thermally efficient, who cares
then they invented the dyno and bsfc so you can get the figures at any rpm in reality not theoretically.
You can get the shaft torque sensors so you can get a torque reading on the dashboard just like rpm these days.
If you arrive at church too early, wait duration will exceed Mass duration but you can maintain prayer intensity in both intervals.
