AI Thread Summary
The discussion focuses on the optimal height for a shot tower used to produce lead bullets through the dripping of molten lead. It emphasizes that traditional designs were based on experience rather than precise calculations, making it challenging to determine the exact height needed. Key factors influencing the tower height include gravity, mechanical energy, and thermodynamics, which affect the lead droplets' cooling and shaping. The goal is to ensure that the droplets solidify into a spherical shape before hitting the water pool. The referenced Wiki sites provide additional insights into the required height and the quenching process.

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 ?
 
Engineering news on Phys.org
I've seen one of these working . The Bristol one as shown in small pictures here :

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
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
