Cylinder:
- 13kg
- 45kg

Price:
- R$

Time spent:
- minutes or hours

Temperature:
- less than 180 ° C
- equal to 180 ° C
- greater than 180 ° C

Spent kg / h:
- 0.200 kg / h
- 0.225 kg / h
- 0.250 kg / h

Example:

= 13kg bottling
Price = 55.00 reais
Spent time = 60 minutes
Unless temperature = 180 ° C
Spent = 0.200 kg / h

Result = ((((0.200 / 60) x60) / 13) x 55)
Spent value = R $ 0.85 reais.
