Electrical
Motor cable voltage-drop check
Turn shaft power, voltage, efficiency and power factor into a running-current estimate, then check cable voltage drop and conductor geometry.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSDC wire selection by voltage drop
Choose a conductor area or maximum one-way cable length for a DC circuit using an explicit voltage-drop budget and wire geometry lookup.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSThree-phase motor power and current check
Separate shaft output, real input power, apparent power and running current for a balanced three-phase motor; carry a checked current into a cable calculation.
Plan the job →Plumbing & Fluid
Pipe sizing and flow check
Move from NPS/DN and schedule to bore, velocity and Darcy pressure loss using a consistent flow and fluid condition.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSPump system head and power check
Combine pipe/fitting loss, elevation and boundary pressure into total dynamic head, then estimate hydraulic, shaft and electrical power.
Plan the job →HVAC & Energy
HVAC duct airflow and size check
Connect room airflow, a stated velocity or friction criterion, and round/rectangular duct dimensions with clear equal-area and equivalent-diameter distinctions.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSHeating load to heat-pump capacity check
Build an envelope and outdoor-air heat-loss estimate, compare a heat-pump capacity basis, then separate peak kW from annual kWh and running cost.
Plan the job →Mechanical / Power Transmission
Shaft torque and key geometry check
Convert power and RPM to shaft torque, compare tangential force at a radius, and look up a documented key geometry for a measured shaft.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSBelt drive speed and geometry check
Check pulley speed ratio, open-belt length and wrap angle from pitch diameters and centre distance before selecting manufacturer belt hardware.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSGear drive ratio and pitch geometry check
Connect tooth-count ratio to output RPM, then verify compatible module/diametral pitch and nominal pitch diameters for a simple gear pair.
Plan the job →Freight & Logistics
Container carton, pallet and payload plan
Combine mixed-carton CBM, pallet fit, container geometry and mass limits into a documented loading estimate with packing and stability limitations.
Plan the job →ENGINEERING WORKFLOW · 3 STEPSAir freight chargeable-weight check
Use packed carton dimensions, actual gross mass and the carrier divisor to compare volumetric and chargeable weights with explicit rounding scope.
