## SprinkCalc Pro Description
SprinkCalc Pro is the professional fire sprinkler calculator every fire protection engineer, sprinkler fitter, and contractor needs on the job site. Get accurate Hazen-Williams friction loss, K-factor discharge, NFPA design area, system volume, hose stream allowance, and antifreeze concentration calculations — all in one app, 100% offline.

Designed for NICET certified professionals, fire protection engineers, and sprinkler system designers who need fast, reliable calculations in the field or at the desk. Every calculation runs on-device with zero connectivity required.

SPRINKLER CALCULATORS:

• Hazen-Williams Calculator — Calculate friction loss in fire sprinkler piping using the Hazen-Williams equation. Supports all standard pipe sizes, C-factors for steel, copper, CPVC, and cement-lined pipe. Essential for every hydraulic calculation.

• K-Factor Calculator — Calculate sprinkler discharge flow rate from K-factor and residual pressure. Covers standard spray (K-5.6), large drop (K-11.2), ESFR (K-14.0 to K-25.2), and all NFPA listed K-factors. Instantly verify sprinkler performance.

• Design Area Calculator — Determine the required design area and water density based on NFPA 13 hazard classifications. Supports Light Hazard, Ordinary Hazard Group 1 & 2, Extra Hazard Group 1 & 2, and ESFR configurations.

• System Volume Calculator — Calculate the total water volume in fire sprinkler piping systems. Enter pipe sizes, lengths, and fitting counts to get precise gallons/litres for system volume. Critical for antifreeze systems, dry systems, and pre-action systems.

• Hose Stream Allowance Calculator — Determine the required hose stream allowance based on NFPA 13 occupancy classification. Ensures your water supply meets the total demand including inside and outside hose streams.

• Antifreeze Concentration Calculator — Calculate the correct glycerin or propylene glycol concentration for antifreeze fire sprinkler systems. Temperature-based lookup per NFPA 13 requirements. Verify freeze protection levels instantly.

REFERENCE GUIDES:

• NFPA Standards Reference — Quick reference for NFPA 13 (Installation), NFPA 14 (Standpipes), NFPA 20 (Fire Pumps), NFPA 24 (Underground Mains), and NFPA 25 (Inspection & Testing). Key requirements at your fingertips.

• Pipe Schedule Reference — Complete pipe schedule tables for Schedule 10, 40, and steel/copper piping used in fire sprinkler systems. Inside diameters, wall thickness, and C-factors for all standard sizes.

• Sprinkler Types Reference — Visual guide to sprinkler head types including pendant, upright, sidewall, concealed, ESFR, and residential. Temperature ratings, K-factors, coverage areas, and application guidelines.

BUILT FOR THE FIELD:

• Calculation History — Recent calculations saved automatically. Review and compare past results across projects.

• Unit Toggle — Switch between Imperial (US) and Metric (SI) units with one tap. PSI/bar, GPM/LPM, feet/metres, inches/mm.

• Dark Mode — Full dark/light mode support for any environment.

• 100% Offline — No internet required. Every calculation and reference runs entirely on-device. Use it on the construction site, in the riser room, or at your desk.

WHO IS THIS FOR:

• Fire Protection Engineers (PE/NICET)
• Sprinkler Fitters & Journeymen
• Fire Sprinkler Contractors & Designers
• Building Inspectors & Plan Reviewers
• Insurance Underwriters & Risk Engineers
• Fire Safety Consultants
• Mechanical Engineers working on fire protection

Built for fire protection professionals by people who understand the industry. SprinkCalc Pro uses NFPA standard formulae and industry-accepted calculation methods — not guesswork. From apprentice to senior engineer, this is the fire sprinkler calculator that belongs in your pocket.
