Blood
alcohol concentration (BAC) is the
concentration of alcohol in blood. It is usually measured as mass per volume.
For example, a BAC of 0.02% means 0.2 ‰ (permille)
or 0.02 grams of alcohol per 100 milliliters of an individual's blood.
In
Suppose that you have gone to a fund-raising
cocktail party where you are allowed to have two free drinks (of any
kind). You have brought two friends with you who are also entitled to the
two free drinks. You are in a hurry so you "slam" the
drinks down -- drink as fast as you can, and then depart. Your
first friend, Jane, weighs 110 pounds, and orders two Cosmos. Your
second friend, Jim, weighs 240 pounds and orders two 12 oz light beers with 4%
alcohol by volume. You order whatever you want. Calculate the
amount of alcohol consumed by each person, and their BAC, including yourself.
Keep at least four digits in your
intermediate calculations.
2. For Jane:
a) Alcoholic content of two Cosmos
(Use the recipe for Cosmo # 1 at http://www.webtender.com/
).
Assume Absolute Vodka of 80 proof = 40%
alcohol and Triple Sec at 48 proof = 24% alcohol.
__________ fluid
oz. of alcohol == __________ milliliters = _________ grams
(For converting milliliters to grams multiply by conversion factor
.79 -- the specific gravity of alcohol in grams per milliliter).
b) Convert Jane's weight from pounds to
kilograms: _____________ kilograms.
c) Calculate the total body water in liters and milliliters for Jane (Women have 49% of
their body weight is water on average, while men have 58% of their body
weight as water.
______________ liters
or _____________ milliliters.
(Note, for water, 1 kilogram = 1 liter.)
d) Compute the concentration of alcohol
in the water in Jane's body in grams of alcohol per milliliter of water.
_____________ grams
of alcohol / milliliter of water
e) Compute the concentration of alcohol in Jane's blood in grams of
alcohol per milliliter of blood. (The percentage of water in the blood is 80.6%).
____________ grams
of alcohol / milliliter of blood
f) Compute the BAC
(in grams/100 milliliter or equivalently grams/deciliter-- we normally
express a percentage).
______________ grams
/ deciliter
g) Should she be allowed to
drive? Justify your answer.
h) Assuming that Jane has an average metabolic rate of .017
per hour decline in BAC. (Range can be as low as .010 and as high as
0.040 -- heavy drinkers (60 or more drinks in
one month) have a metabolic rate of 0.020).
What is her BAC after 30 minutes?
__________ After 2 hr.? ____________
3. Compute Jim's BAC in the same
manner.
a) Alcoholic content
of the two 12 oz 4% beers
_______ fluid oz. of alcohol ==
__________ milliliters = _________ grams
(For converting milliliters to grams use the conversion factor .79
-- the specific gravity of alcohol in grams per milliliter).
b) Convert Jim's weight from pounds to
kilograms: _________
kilograms.
c) Calculate the total body water in
milliliters for Jim (Women have 49% water on average, while men 58% ).
__________ milliliters
d) Compute the concentration of alcohol
in the water in Jim's body in grams of alcohol
per milliliter of water.
_____________ grams
of alcohol / milliliter of water
e) Compute the concentration of alcohol
in Jim's blood in grams of alcohol per milliliter of blood. (The
percentage of water in the blood is 80.6%).
____________ grams
of alcohol / milliliter of blood
f) Compute the BAC
(in grams / deciliter)
___________
g) Should he be allowed to drive?
h) Assuming that Jim has an high metabolic rate
of .020 per hour decline in BAC. (Range can be as low as .010 and
as high as 0.040 -- heavy drinkers (60 or more
drinks in one month) have a metabolic rate of 0.020).
What is his BAC after 30 minutes?
__________ After
2 hr.? ____________
4. Now compute your BAC in this
same situation.
List the drinks your chose with alcohol quantities used to make the drink (Use
the recipe at http://www.webtender.com/
) below:
a) Alcoholic content
of two drinks.
_______ fluid oz. of alcohol ==
___________ milliliters = _________ grams
(For converting milliliters to grams use the conversion factor .79
-- the specific gravity of alcohol in grams per milliliter).
b) Convert your weight from
pounds to kilograms:
_________ kilograms
c) Calculate the total body water in
milliliters for yourself. (Women have 49% water
on average, while men 58%).
__________
milliliters
d) Compute the concentration of alcohol
in the water in your body in grams of alcohol
per milliliter of water.
_____________
e) Compute
the concentration of alcohol in your blood in grams of alcohol per milliliter
of blood. (The percentage of water in the blood
is 80.6%).
____________
f) Compute the BAC (in grams/deciliter).
_______________
g) Should you be allowed to drive?
h) Estimate your metabolic rate for
alcohol __________
Using this, what is your BAC after 30
minutes? __________ After
2 hr.? ___________
5. a)
What is the level of BAC that normally produces alcohol poisoning (including
risk of death)? __________
See the following site: http://www.factsontap.org/factsontap/naked_truth/by_the_numbers.htm
b) Bonus (4
points): For Jane’s characteristics, how many
ounces of "instantaneously" consumed 80 proof whiskey would produce
this level? (Show work below) . Hint:
This can be done by solving a simple equation using ratios and your
previous computations for Jane.
__________ ounces
of 80 proof whisky.
