[1] For a fuel of composition C c H h O o N n , the (higher) heat of combustion is 419 kJ/mol × ( c + 0.3 h − 0.5 o ) usually to a good approximation (±3%), [ 2 ] [ 3 ] though it gives poor results for some compounds such as (gaseous) formaldehyde and carbon monoxide , and can be significantly off if o + n > c , such as for glycerine ...
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR).. The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight.
If you want to gain weight, aim to add half a pound per week. Establish your caloric deficit. There are 3,500 calories in a pound of fat, so you’ll divide that number by seven (for the days in ...
Basal metabolic rate is the amount of energy per unit of time that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. Basal metabolic rate affects the rate that a person burns calories and ...
