what is kcal/h?

Answer 1

it is a measure of POWER. 1 kcal/h can raise 1000 cc of water 1 degree C in 1 hour, or 2000 cc of water 1 degree in 1/2 hour, or 1000 cc 2 degrees in 1 hour or 2000 cc 4 degrees in 1/8 of an hour, etc.

It has nothing to do with ENERGY, this is a POWER unit. Energy/time is POWER....POWER...POWER.

Energy is how much work is done...POWER is how FAST the work is done.

Energy how MUCH work...Power is how FAST work is done.

Ok, hopefully I have beat this one to death.

Answer 2

Kcal Means

Answer 3

Lets start from the beginning using SI units.

1 W = 1 J/s = 1 newton meter per second = 1 kg·m2·s−3

1 Kw.Hr = 1000 * 60*60 = 3600000 J

1 Cal = 4.1868 J

1 kcal = 1000 * 4.1868 = 4186.8 J

That means kcal/hr = 4186.8 /(60*60) = 1.163 w

Unless you mean kcal.hr which equal to=4186.8*60*60=15072480 J = 4.1868 Kw.hr

J – Joule
W – watt
Cal-calorie
S- second
Kg – kilogram
m- meter
Hr- hour =3600 seconds
K – kilo =1000

Answer 4

kcal/hr means kilocalorie per hour. It is a dimention of POWER which amounts to about 337 horsepower or about 251 kilowatt.

Answer 5

kilo-calories per hour. Small calories that is. Common food is measured in Calories where 1 Calorie = 1000 calories = 1 kcal.

Answer 6

I believe it is Kilocalories per hour, having to do with the metabolic rate...can anyone back this up?

Answer 7

means: kilocalorie per hour
1 kilocalorie / Planck's constant = 6.31445376 × 1036 hertz

Answer 8

It is the amount of work needed to increase one liter of water one degree centigrade for one hour.

Answer 9

kilocalories per hour

Answer 10

kilocalories per hour
