03The connected KEVOS® ecosystem
Learn. Apply. Improve.
KEVOS® connects technical knowledge with practical tools, helping people move from understanding a concept to applying it in real-world situations.
Learn and understand
Read the method, the reasoning and the worked numbers behind a decision.
Calculate, analyse and apply
Enter your own figures, check the result and keep a report of what you decided.
Describe it, discover it
Describe a problem in your own words at the top of this page. KEVOS® suggests the tools and Library chapters that fit; the tools do the calculating.
Today, 905 reviewed links connect Library books and chapters with the tools that apply them. These learning pathways take you from a chapter to a tool:
Appraise an equipment investment
Learn what NPV, IRR and payback each answer, then appraise a purchase with your own figures.
- Learn
- NPV, IRR and payback answer different questions: reading investment measures when they disagree in Investment Appraisal and Business Cases
Develop a flat blank for a bent part
Learn how the neutral axis and K-factor set bend allowance, then size the blank for your own bend.
- Learn
- Neutral axis, K-factor and bend allowance in Sheet Metal Parts by the Numbers
Measure and value equipment losses
Learn how OEE separates availability, performance and quality losses, then analyse a production period of your own.
- Learn
- Measuring productivity: output per input, labour measures and overall equipment effectiveness in Lean, Maintenance and Continuous Improvement
Find what compressed-air leaks cost
Learn how pressure setting and leaks waste compressor energy, then audit the leaks in your own system.
- Learn
- Set the pressure and stop the waste in Compressed Air Plant by the Numbers
Check whether a cold surface will sweat
Learn how vapour pressure sets the dew point, then check your own surface against it with a margin.
- Learn
- Water in air: vapour pressure, humidity and dew point in Condensation Control by the Numbers
Measure how wet your steam is
Learn what dryness fraction means and how a throttling calorimeter measures it, then work out the dryness from your own reading.
- Learn
- Reading the steam table in Process Steam by the Numbers
