Pipe Burst Working Pressure Calculator is a physics/math tool designed to calculate fluid pressure, pipe wall thickness, pipe outside diameter, safety factor, or material strength. Features: - Instant calculations. - Results can be copied to other apps. - Formulas included for reference. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. To find the burst pressure of a pipe, Barlow's Formula is used, along with associated equations to determine the working pressure of a pipe with a known diameter. Barlow’s Formula establishes the relationship between internal pressure, allowable stress, nominal thickness, and diameter. Equation: P = (2*S*T)/(OD*SF) Where: P = Fluid Pressure (psi) T = Pipe Wall Thickness (in) OD = Pipe Outside Diameter (in) SF = Safety Factor (for general calculations, use 1.5 – 10; use 1 for bursting pressure) S = Material Strength (psi), minimum yield strength Thank you for your support!
