Primaria Calorie Burning

[Atlantic717]

The human body converts internal chemical energy into work and heat at rates of 60 to 125 W (called the basal metabolic rate). This energy comes from food and is usually measured in kilocalories [1 kcal = 4.186 kJ]. (Note that the nutritional `Calorie' listed on packaged food actually equals 1 kilocalorie). How many kilocalories of food energy does a person with a metoblic rate of 102.0 W require per day? (Assume 100 percent efficiency.)

Re: Calorie Burning

Hola Atlantic717:

Se resuelve simplemente aplicando las relaciones:

1 día: 86400 segundos
1 W = 1 J/s

$<br /> cal/dia = 102,0\frac{J}{seg} 86400\frac{seg}{dia} \frac{1}{4,186}\frac{cal}{J}<br />$

esto da 2105300 cal o sea 2105,3 Kcal
