That depends - it varies from individual to individual. The amount of blood pumped per minute (cardiac output) is calculated by taking the heart rate and multiplying by the amount of blood ejected from the heart per beat (stroke volume). Normal heart rate is between 60-100 for an adult and stroke volume is in the neighborhood of 70-120ml usually.

The blood travels around the body and back to the heart in about one minute if the person is at rest. The heart beats 70 times a minute, with each beat the heart pumps 60 to 90 mililiters (2 to 3 ounces) of blood out of the heart. It can move 5 to 7 liters of blood in one minute and 7600 liters (2000 gallons) per day. In a lifetime, it beats over 2.5 billion times and pumps over 200 million liters of blood. Infants have slightly faster heart beat than an average person, their heart beats 120 times per minute. Physical activities will also increase the heart rate.
The heart is the most important muscle in the human body, it works 24 hours a day. It keeps us alive by pumping oxygen rich blood to the whole body. People can keep their heart healthy by exercising regularly.

CO= HR x SV
Cardiac output (CO) is the amount of blood pumped by the heart in one minute. You can calculate your CO if you multiply your heart rate, by the Stroke Volume (SV), which is the amount of blood pumped by the ventricle. The average resting Stroke Volume is about 70ml, and the average heart rate is 60 - 80 beats per minute. But remember that SV and HR depend on so many things that you cannot really be given a specific number.
If you are feeling adventurous, you could multiply the CO by 60, to get hourly volume and them multiply that by 24, to get daily volume. But even then it would still be a guesstimate.

Males on average have 5 liters of circulating blood, Females 4 liters. It takes only a minute for your body to circulate your entire blood supply. Pretty cool huh.

The human body has about 16 pints of blood in it, and that cycles over and over again throughout the body.
