Cable Size Calculator: How to Calculate Cable Size for Electrical Installations
Selecting the correct cable size is critical for electrical safety and efficiency. Undersized cables overheat and can cause fires; oversized cables waste material cost. This guide explains the two-step calculation method — current capacity check plus voltage drop check — with worked examples for motors, panels, and distribution circuits.
Flow Rate Calculator: How to Calculate Pipe Flow Rate, Velocity and Volume
Flow rate calculation is fundamental to pipe sizing, pump selection, and process design. This guide covers the Q = A × v formula, velocity limits for different fluids, unit conversions between m³/s, m³/h, L/min, and GPM, and how to use a flow rate calculator for industrial piping.
How to Calculate Motor Power: kW, HP and Torque Explained
Selecting the wrong motor size wastes energy or burns out equipment. This guide explains the motor power formula, how to convert between kW and HP, account for efficiency losses, and size a motor correctly for your application.
Pump Sizing Calculation: Flow Rate, Head and Power Explained
Selecting the wrong pump wastes energy, causes cavitation, or fails to deliver the required flow. This guide walks through pump sizing step by step — from calculating total head and flow rate to selecting the correct pump and motor.
How to Calculate Production Cost Per Unit: Formula and Examples
Knowing your cost per unit is the foundation of pricing, quoting, and profitability. This guide explains the production cost per unit formula, how to classify each cost element, and how to build a complete unit cost calculation for any manufactured product.
Pipe Pressure Drop Calculation: Darcy-Weisbach Formula Explained
Pressure drop in pipes directly determines your pump size and energy cost. This guide explains the Darcy-Weisbach pressure drop formula, how to find the friction factor, and how to account for fittings and valves in your pipe system design.
How to Calculate Depreciation for Plant and Machinery
Depreciation is a real cost of owning plant and machinery — if you ignore it in your project costings, you are underpricing your work. This guide explains the three depreciation methods, the formula for each, and how to apply the correct rates for plant and equipment.
Welding Cost Calculation: Electrode, Labour and Gas — Complete Guide
Welding cost is one of the most underestimated expenses in fabrication projects. This guide breaks down every component of welding cost — consumables, labour, gas, power, and overhead — with worked examples for MIG, TIG, and stick welding.
Compressed Air System Sizing: How to Calculate CFM and Pipe Size
Compressed air is the fourth utility in most factories — and the most expensive per unit of energy delivered. Sizing the system correctly reduces energy waste, prevents pressure drops at tools, and avoids costly compressor oversizing.
Heat Exchanger Sizing: How to Calculate Area and Flow Rate
Heat exchanger sizing determines how much area you need to transfer the required heat between two fluid streams. This guide walks through the LMTD method step by step with worked examples for shell-and-tube and plate heat exchangers.
Lean Manufacturing KPIs: How to Measure Plant Performance
Lean manufacturing is built on measurement. If you cannot measure it, you cannot improve it. This guide explains the 10 essential lean manufacturing KPIs, how to calculate each one, and what target values to aim for in a high-performing plant.
Cable Size Selection Guide: How to Select Cable Size in mm² for Any Load
Selecting the wrong cable size is one of the most common — and costly — mistakes in industrial electrical installations. This guide walks through the exact two-step method (ampacity + voltage drop) used by electrical engineers to select cable size in mm² for any load.
Warehouse Storage Capacity Planning: How to Calculate How Much Space You Need
How much warehouse space do you actually need? This guide shows you how to calculate storage capacity from your inventory in pallets, choose the right racking system, and design a layout that maximises both density and operational efficiency.
Transformer KVA Sizing Guide: How to Select the Right Transformer for Your Factory
Undersizing your transformer creates voltage sag, overheating, and frequent tripping. Oversizing wastes capital and increases no-load losses. This guide shows the exact method to calculate the correct transformer KVA rating for a factory or industrial facility.
Diesel Generator Sizing Guide: How to Calculate DG Set KVA Requirement
Selecting the right DG set size is critical — too small and it trips on overload when large motors start; too large and it wastes capital and fuel. This guide shows the complete method for calculating diesel generator KVA, including motor starting load that most engineers miss.
