Water tanks are often used in forensic ballistics to simulate the effects of shooting into water, which can help determine the trajectory of a bullet and the extent of damage caused by a projectile. By analyzing the behavior of bullets fired into water tanks, forensic experts can gather valuable evidence to reconstruct shooting incidents and make interpretations about the weapon used.

Why are bullets fired into a gel tank in a forensics ballistic lab?
Bullets are fired into a gel tank in a forensics ballistic lab to simulate the impact of a bullet on human tissue. The gel, usually ballistic gelatin, has similar density and consistency to human tissue, allowing investigators to study the behavior of the bullet upon impact. This helps in determining the trajectory, penetration depth, and potential damage caused by a fired bullet.
What are the forces acting on water tank?
The main forces acting on a water tank are gravity, buoyancy, and the pressure of the water inside the tank. Gravity pulls the water downward, creating pressure at the bottom of the tank. Buoyancy pushes upward on the tank walls, counteracting the force of gravity.
Pressure in a pipe draining an elevated water tank depends on the height of the tank but does it also depend on how full the tank is?
Yes, the pressure in a pipe draining an elevated water tank depends on both the height of the tank and the level of water in the tank. The pressure is directly related to the height difference between the water level and the point of discharge, and it decreases as the water level in the tank drops.
When you start unscrew a ballcock what happens?
When you start to unscrew a ballcock, you are essentially loosening the connection between the ballcock and the water supply line. This allows you to either remove the ballcock for maintenance or replacement, or to adjust the float level to control the water level in the tank.
Is the water in the kettle or tank storing the greatest amount of heat energy?
The water in the tank typically stores the greatest amount of heat energy, as it has a larger volume compared to the water in the kettle. The tank water takes longer to heat up but retains heat for longer periods.
Is it possible for water to have two different water levels in one tank?
If they are in a divided tank and there is no open connection between the two sides.
Why is ground wire connected to hot water connection on water heater?
So the tank is grounded.
what is the connection OD?
It is a connection that is part of the nozzle of a propane tank.
What is the new design for water heaters?
In many American water heaters the cold water IN connection is now routed to the bottom of the tank (as opposed to both on top as used to be. ) .
Can a leaky hot water heater be repaired or does it need to be replaced?
If the leak is from the tank itself and not a connection, it's time to replace it.
What is a tricock valve?
It is a small, valve usually used to manually check if water is above the valve connection on a boiler or tank. There may be several of them at different heights on the boiler or tank. There is a handwheel on the valve, an inlet connection (which is attached to the boiler) and an outlet (usually left unconnected). When filling the boiler or tank, the try-cocks can be left open. Water coming from the try-cock means the tank is filled to at least that level. The valve is then closed.
Where is the low service port on a 1997 Monte Carlo?
remove window wash fluid tank to acess ports, look under water exit electrical connection on tank to view
What were examples of new technology in the war?
2 are: Bullet-Proof Vests and Artificial Rubber.
Why are bullets fired into a gel tank in a forensics ballistic lab?
Bullets are fired into a gel tank in a forensics ballistic lab to simulate the impact of a bullet on human tissue. The gel, usually ballistic gelatin, has similar density and consistency to human tissue, allowing investigators to study the behavior of the bullet upon impact. This helps in determining the trajectory, penetration depth, and potential damage caused by a fired bullet.
What does ballistic mean?
Ballistic refers to the science or study of the motion of projectiles, like bullets or rockets, especially in flight. It can also describe a free-flying object moving solely under the force of gravity or the trajectory of such an object.
What does a Wessex flange look like in plumbing?
Which pipe connects to where on the Wessex flange i.e. feed to pump connection and feed to expansion tank and hot water taps?
Why do you need to have a water tank?
If water doesn't go into the pressure tank you will not have water pressure.
