The force of the blood hitting a surface for medium velocity blood spatter is between 5 and 100 feet per second. Produced with more energy or force than gravity The force of the impact causes the blood to break into smaller size spatters relative to the amount of force applied This type of spatter is usually seen in blunt force stabbings and secondary spatters Produced when the majority of larger drops of blood are. As an attempt to represent the variability expected of such patterns different methods of pattern creation were utilised.

An investigation of the influence of droplet impact velocity and number of droplets on static pattern features. Caused by an impact of 100 feet per second. Is never used for descriptive purposes.

These are small drops with diameters of 1 to 4 millimeters. Medium Velocity An external force of greater than 5 fps but less than 25 fps causes medium blood spatter. High velocity blood spatter.

Impact Pattern - A bloodstain pattern resulting from an object striking liquid blood. The findings from the analysts observations suggest that caution. High velocity blood spatter is usually caused by a gunshot it can also be caused by other objects too if enough force is exerted.

The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source. Asked Jun 28 2016 in Criminal Justice by Ligia. 2 Medium-velocity spatter is often accompanied by cast-off blood since blunt-force attacks with an object are involved.
