Since the blood flow of the IJV (internal jugular vein) is 700mL per minute when the head is lying flat, and at 70mL per minute when the head is at a right angle, and you need to lose approximately 40% of your blood to die, when the vein is cut it would take around 3 minutes to bleed out and die if the head is flat, and about 30 minutes to bleed out if the head is bent at a 90 degree angle. these numbers are further lengthened if a tourniquet or other blood loss device is applied.

It takes about 2 minutes to bleed to death if the internal jugular vein is cut, which is larger than the external jugular vein, and the victim is in a lying down position, as body posture greatly affects the rate of blood loss. If it's only the external jugular that's cut, then maybe you bleed to death within about 5 minutes. If both the external and internal jugular vein and carotid artery are cut, you probably bleed to death in about 1 minute. The rapid blood loss from the jugular veins is due to their relatively large size and the reflux of blood flowing back the other way because the valves in the jugular veins don't prevent the reflux of blood. Air bubbles can also enter the jugular veins when cut causing an air embolism which can also be lethal.
