A 1 kg mammal uses about 5 kcal of energy per hour (metabolic rate). It eats hay, which contain about 2000 kcal per kg.
a. Write out the equation to calculate how much energy it uses per week:
b. Write out the equation to determine how many kg of hay this mammal must eat per in a week to maintain its body weight
c. Write out the equation to determine how long it will take this mammal to burn 0.1 kg of fat, assuming that fat yields 9 kcal/gram

A
human requires about 2000 kcal per day. Suppose that all of that
energy comes from pure sugar, which contains 4.0 kcal/g.
A) How many grams of sugar would a person need in a day?
Approximately how much would they consume a year?
B) Glucose has the chemical formula C6H12O6. If a molecule of
glucose is broken down into pure CO2 and water, how many molecules
of each would it make?
C) Carbon has a molecular weight of 12, hydrogen...

The metabolic energy generated in the person is
3.8x106 J in a 6 hour period, and this is balanced by
cooling of the body by 2.6 L of perspiration and radiative cooling
(you can neglect conductive and convection cooling). What is the
effective surface area of the person?

1) When people sleep, their metabolic rate is about 2.6 * 10^-4
C/(s*kg). How many Calories does a 81 kg person metabolize while
getting a good night's sleep of 8.5 hrs?
2) To determine the specific heat of an object, a student heats
it to 100 °C in boiling water. She then places the 34.5-g object in
a 151-g aluminum calorimeter containing 114 g of water. The
aluminum and water are initially at a temperature of 20.0 °C, and

Osborn Manufacturing uses a predetermined overhead rate of
$18.30 per direct labor-hour. This predetermined rate was based on
a cost formula that estimates $221,430 of total manufacturing
overhead for an estimated activity level of 12,100 direct
labor-hours.
The company incurred actual total
manufacturing overhead costs of $217,000 and 11,600 total direct
labor-hours during the period.
Required:
1.
Determine the amount of underapplied or overapplied
manufacturing overhead for the period.
2.
Assuming that the entire amount of the...

Cretin Enterprises uses a predetermined overhead rate of $21.40
per direct labor-hour. This predetermined rate was based on a cost
formula that estimated $171,200 of total manufacturing overhead for
an estimated activity level of 8,000 direct
labor-hours.
The company incurred actual total manufacturing overhead costs
of $172,500 and 8,250 total direct labor-hours during the
period.
Required:
1. Determine the amount of underapplied or overapplied
manufacturing overhead for the period.

Osborn Manufacturing uses a predetermined overhead rate of
$20.20 per direct labor-hour. This predetermined rate was based on
a cost formula that estimates $282,800 of total manufacturing
overhead for an estimated activity level of 14,000 direct
labor-hours.
The company actually incurred $279,000 of manufacturing overhead
and 13,500 direct labor-hours during the period.
Required:
1. Determine the amount of underapplied or overapplied
manufacturing overhead for the period.
2. Assume that the company's underapplied or overapplied
overhead is closed to Cost of...

A vehicle burns gasoline (density = 0.79 kg/liter) at a rate of
7.6 liters per hour. Although gasoline is a mixture of many
chemicals, for simplicity assume it has the formula of octane,
C8H18.
What is the required air flow rate in molar units (kmol/hr),
in mass units (kg/hr) and in standard volume units (standard m3/hr)
for air fed in stoichiometric proportion?
Determine the flowrate (kmol/hr) and composition (mol
fraction) of the exhaust gases if 25% excess air...

Metabolic rate, the rate at which the body consumes energy, is
important in studies of weight gain, dieting, and exercise. The
provided table gives data on the lean body mass and resting
metabolic rate for 12 women and 7 men who are subjects in a study
of dieting. Lean body mass, given in kilograms, is a person’s
weight leaving out all fat. Metabolic rate is measured in
kilocalories (Cal) burned per 24 hours, the same calories used to
describe the...
