    Tower
In summary, the shot tower used to make lead bullets consists of a tall tower where molten lead is dripped from the top and solidifies into small round pellets before reaching the bottom. The tower must be tall enough for the droplets to cool and form into spheres before reaching the bottom. The design of shot towers is based on experience rather than calculations, and it is difficult to calculate the required height. The Bristol shot tower is a famous example and there is a much older one still in operation.

Can someone help my problem

Grains of lead bullets used in rifle cartridge made of small round pellets 2-3mm in diameter and is made by dripping molten lead from a tall tower , this method has been used since its invention by William Watts in 1782. To produce granules of lead ball must be ensured droplets copper liquid freezes before reaching the runway . How high should we build a tower ?

I've seen one of these working . The Bristol one as shown in small pictures here :
https://en.wikipedia.org/wiki/Shot_tower

More about the Bristol one here :

This is a much older one in action :


To answer your question - shot towers were always designed by experience rather than by calculation .
Meaningful calculations would in any case be very difficult to do . A computer model might be possible .

Note that shot towers were always very high .

Ok, in my case should calculate high the tower. It use many factors like gravity, mechanical energy, or thermodynamics. I stuck with that. But thank you Nidum for this information it will helpful

The referenced Wiki site give you the required height and clarifies the method of quenching and transport. The tower height is what is required to only to allow the lead droplet to configure into a spherical shape and then cool to the point that it will not deform upon striking the water pool.

Thank you your explanation JBA
 

1. How does the height of a tower affect the speed of a lead bullet?

The height of a tower does not directly affect the speed of a lead bullet. The speed of a bullet is determined by factors such as the gunpowder used and the barrel length of the gun.

2. Is there an optimal tower height for lead bullets?

There is no specific optimal tower height for lead bullets. The height of a tower may vary depending on the specific experiment or testing being conducted.

3. Can different tower heights produce different results for lead bullets?

Yes, different tower heights can potentially produce different results for lead bullets. This is because the height of the tower can affect the angle at which the bullet is fired and the trajectory it takes.

4. How does the height of a tower impact the accuracy of lead bullets?

The height of a tower may have a minimal impact on the accuracy of lead bullets. Other factors such as wind, distance, and shooter skill have a greater impact on bullet accuracy.

5. Is there a formula for determining the ideal tower height for lead bullets?

There is no specific formula for determining the ideal tower height for lead bullets. It may vary depending on the specific experiment or testing being conducted.
