Engineering tools

Plant Room Studio — MEP Tools — Plan, coordinate and validate MEP plant-room layouts in 2D and 3D. Position electrical, mechanical and plumbing equipment, define maintenance access, check clearances and prepare coordinated outputs from one workspace.
Voltage Drop & Cable Size Checker — MEP Tools — Size LV cables and verify voltage drop using BS 7671 data or custom impedance values—with formulas, source tables, and calculation assumptions clearly shown.
Duct Pressure Drop Calculator — MEP Tools — Estimate single-duct-run pressure drop: Darcy-Weisbach friction (Swamee-Jain), Huebscher equivalent diameter for rectangular ducts, and fitting losses via Sigma K or a fitting schedule - with velocity, Reynolds number, flow regime and Mach shown.
Water Pipe Pressure Drop & Pump Head Calculator — MEP Tools — Calculate water-pipe velocity, Reynolds number, Darcy–Weisbach friction loss, fitting losses, total dynamic head and pump power. Enter your own pipe properties and fitting K-values, with every formula, assumption and calculation step clearly shown.
