Practical calculators for cable sizing, voltage drop, power and electrical design checks.

Power

Public Health

Water demand, flow, storage and pipe sizing calculators for public health engineering design work.

Water

Design Workflows

Heating Flow

Follow the typical hydraulic design path from duty through to vessel sizing.

Ventilation Design

Move from fresh air requirements through to duct sizing, pressure drop and fan power checks.

Electrical Design

Move from load assumptions through to voltage drop and cable sizing.

Water Systems

Start from demand, then move through flow, pipe sizing and storage.

MEPkit provides indicative engineering tools for preliminary design, feasibility checks and day-to-day calculation support. Final design should always consider project-specific requirements, manufacturer data, applicable standards, and detailed system constraints.
