Out for blood: Fluid dynamics explain how quickly a vampire could drain your blood
Throughout human history there have been tales of vampires -- bloodsucking creatures of folklore that prey on their victims by draining their life essence, usually via the blood. To coincide with the 85th anniversary of Tod Browning's 'Dracula' (1931), students have used fluid dynamics to examine how long it would take for the undead fiend to drain an average human's blood -- and have calculated that it would take only 6.4 minutes to drain 15 per cent of the blood from the external carotid artery in a human's neck.
