Question
##### Determine an example of a design of a compressed air system, which uses the criterion of speed for the design of the pipes (formula attached). The demands of flow rate, power as well as air velocity in the pipelines can be freely chosen.
- Sizing the compressor (flow, power...)
- Size reservoir required
- Setting the dryer
- Determine the amount of water withdrawn from the system due to air compression
**With the attached formula you can choose the appropriate values of the unknowns
