English students solve the problem

Vampires are a legendary creature, it becomes a phenomenon caused by superstition fanaticism. Vampires act primarily by biting the victim's neck and sucking blood from the arteries.

Vampires exist by sucking fresh blood.

A group of students in the Department of Physics, University of Leicester calculated how long a Vampire needs to be able to drain the victim's blood, resulting in about 6.4 minutes. They published their research in the Journal of Physics Special Topics of Leicester University.

The human body will no longer function if a large amount of blood is lost. After the body has lost 15% of its blood volume, the heart rate begins to subside. And drinking blood will slow down even when Vampires draw blood from the carotid artery.

Students in Leicester will calculate how long 15% of human blood will be sucked out with just a few small holes in the neck.

Students made several assumptions to reduce their analysis of content. The first assumption, they assumed that Vampires had no intention of killing a person, they just wanted to drink a bit of blood to maintain life and would leave immediately before there was a person holding garlic and a tree. the cross comes.

The second assumption, they argue, is that the gravity of blood in the human body is negligible if compared to the pressure of the circulatory system , they rely on this assumption to calculate the speed of blood drawn from the arteries.

The final assumption, they argue, is that the rate of blood drawn out is stable because every year when arteries are drawn out by the aorta are equal in size.

By assumptions and calculations on the speed, they calculated the speed of blood drawn out through the arteries. They found that Vampires will create two 0.5 mm diameter holes to suck blood, and 15% of the body's blood will be sucked in 6.4 minutes.

This research will assist you in writing a novel or making movies about Vampires. And if you happen to meet Vampire, calculate the standard time so you won't get all the blood in your body.
