How much energy does it take to make a glass bottle?

The energy required to make a glass bottle can vary depending on factors such as the size and shape of the bottle, the type of glass, and the production process used. Generally, it takes around 4,000 to 6,000 British Thermal Units (BTUs) of energy to produce a single glass bottle.


How do you calculate the overcapacity of blank mold of glass bottle?

To calculate the overcapacity of a glass bottle blank mold, you would measure the volume of the mold cavity and compare it to the actual volume of the glass bottle being produced. The overcapacity is the difference between the mold cavity volume and the required volume of the glass bottle to account for any variations in glass expansion during the manufacturing process.


When A (ordinary) glass bottle is filled to the brim with mercury. If the temperature of both the bottle and mercury are increased by 19.3oC what fraction of the mercury will spill out of the bottle?

When the temperature of the glass bottle and mercury increases, the volume of both also increases. However, since mercury has a greater coefficient of volume expansion than the glass, it will expand more, causing it to spill out of the bottle. The fraction that will spill out can be calculated using the coefficients of volume expansion for mercury and glass, along with the initial volume of mercury and bottle.


Is a clear glass bottle an opaque?
