Can I customize pipe materials and diameters? What about insulation?

MECHA is designed so every specialist can build their own working set.

Can I size pipes based on velocity?

Sure! And, if you want, you can also apply a pressure-drop limit.

Can I estimate flow rate in a pipe when pressure drop is known?

Absolutely yes! You also get feedback on exchanged power when needed.

Can I calculate pressure drop with water-glycol mixtures at different temperatures and concentrations?

MECHA is exactly what you need: change temperature and concentration, then find the diameter that best matches your criteria!

Our company uses a specific water-glycol mixture: can I use it in MECHA?

Of course! Just edit the .csv file in your library.

I am tired of recalculating pipe weight and insulation area every time. Can MECHA help?

We know the pain! That is why quantity takeoff in MECHA is super convenient: just enter linear pipe length and specify insulation and finish. In the end, you get a full report with all the data you need (also grouped).

Can I customize duct materials and related insulation?

MECHA is designed so every specialist can build their own working set.

Can I size ducts based on velocity? Can I also change altitude and air temperature?

Sure! And, if you want, you can also apply a pressure-drop limit.

How does automatic duct sizing work?

For circular ducts, MECHA automatically calculates the diameter that meets your velocity and/or pressure-drop criteria. For rectangular ducts, you enter one side and MECHA computes the other. If entering one side every time is boring, change values with the mouse wheel: it is much faster! 😉

Our company only uses 25 mm increments for rectangular ducts. Can I set MECHA this way?

Yes! MECHA will determine dimensions while respecting the selected increment multiples.

Can I display psychrometric properties on a Mollier chart?

Of course, yes.

Steam systems

How does MECHA calculate saturated steam properties?

MECHA is designed according to IAPWS-R7-97(2012) guidelines: 100% confidence.

Can MECHA size piping also for saturated steam?

Yes, based on pressure drop and velocity criteria.

I find it tedious to determine flash steam downstream of steam traps to size piping. Can MECHA help?

Absolutely! In fact, MECHA not only calculates flash steam, it also sizes the piping. Just enter pressures and flow rate: easy!

BIM modeling

System sizing

Back to top

I am a modeler and my specialist asked me to size pipes with a max velocity of 1.5 m/s. Can MECHA help?

Perfect! Just set maximum velocity to 1.5 m/s and you are done. You can use the mouse wheel to change diameter or use automatic sizing.

The company I am working for uses a proprietary piping set. Can I import it into MECHA?

Sure! MECHA includes a dedicated app for exactly this. That way your sizing stays fully aligned with your client requirements.

Sizing ducts is painful, because I have to enter both sides every time in a spreadsheet.

MECHA is designed exactly for you: enter flow rate, enable automatic sizing, and use the mouse wheel to modify one side while MECHA computes the other. Then you only update flow rate and MECHA recalculates everything!

Psychrometrics

Air conditioning and ventilation

Back to top

I want to quickly calculate psychrometric conditions and show them on a Mollier chart.

In MECHA there is a dedicated quick panel for that. All properties are based on ASHRAE theory. You also get an interactive Mollier chart.

Can I quickly modify psychrometric properties and compute the others?

Yes! Use the mouse wheel to edit a property (temperature, absolute or relative humidity, enthalpy, etc...).

Heating and cooling plant rooms

Engineering firms

Do you need to quickly size the main plant-room components?

In MECHA you can size all key plant-room components: storage and expansion vessels, safety valves, and distribution headers.

Do you need to enter all quantities in a bill of quantities, split by size, material, and type?

With MECHA you can easily generate a report with similar items grouped together, speeding up the most tedious phase of design.
