MechBundle brings pipe sizing calculators, P&ID tag generation, equipment datasheets, and compressor package references into one place — built by an engineer who was tired of rebuilding the same spreadsheets.
Each calculator gets its own page with the tool up front and the assumptions behind it laid out.
Sizing and package-level calculations for reciprocating and centrifugal compressors.
02Head, flow, and NPSH calculations for pump package selection.
03Cooling load, chilled water flow, and capacity calculations.
04Round and rectangular duct sizing from airflow and velocity or friction rate.
05Airflow and coil load calculations for air handling units.
