A heart pumps about 5 quarts of blood through its chambers every 60 seconds. A swimming pool (20 ft. by 60 ft.) will hold about 65,000 gallons of water. This represents the amount of blood pumped by your heart in approximately how many weeks? (Remember you can have a partial week)
amount=volume/rate=65,000/(1.2/60)= 65,000*60/1.2 seconds
convert that to weeks.
5qts * 1gal./4qts * 1/60s = 0.0833 gal./s.
T = 65,000gal. * 1s/0.0833gal * 1h/3600s = 216.67 Hours.
T = 216.67h * 1day/24h * 1wk/7day = Weeks.
To find the number of weeks it takes for a heart to pump the same amount of blood as the volume of a swimming pool, we need to convert the volume of the swimming pool from gallons to quarts and then divide it by the amount of blood that the heart pumps in one minute.
First, let's convert the volume of the swimming pool from gallons to quarts:
1 gallon = 4 quarts
So, 65,000 gallons = 65,000 x 4 = 260,000 quarts.
Now we can calculate the number of weeks it takes for the heart to pump the same volume of blood as the swimming pool:
Heart pumps 5 quarts every 60 seconds.
This means it pumps 5 x 60 = 300 quarts in one minute.
Therefore, in one week (assuming 7 days), the heart will pump 300 x 60 x 24 x 7 = 3,024,000 quarts.
To find the number of weeks, we can divide the volume of the swimming pool by the volume of blood pumped by the heart in one week:
260,000 quarts / 3,024,000 quarts = 0.0859.
Therefore, it takes approximately 0.0859 weeks for the heart to pump the same amount of blood as the volume of the swimming pool.
