How to Use the Plumbing Calculator
This professional tool helps solve common plumbing calculations:
- Select Calculation Type: Choose between pipe sizing, flow rate, or pressure drop
- Enter Known Values: Input fixture units, flow rate, or pipe dimensions
- Calculate: Get accurate plumbing system specifications
Plumbing Formulas Used
- Pipe Sizing: Based on IPC fixture unit tables
- Flow Rate: Q = 2.448 × v × d² (v = velocity, d = diameter)
- Pressure Drop: hf = f × (L/D) × (v²/2g) (Darcy-Weisbach equation)
- Water Supply: Hunter's Curve for fixture unit calculations
Why Calculate Plumbing Parameters?
- ✅ Proper Sizing: Avoid undersized or oversized pipes
- ✅ Water Efficiency: Maintain adequate pressure and flow
- ✅ Code Compliance: Meet IPC/ANSI standards
- ✅ Cost Savings: Optimize material usage
