## About Hose Flow Rate Calculator (Formula)

The Hose Flow Rate Calculator is a tool used to estimate the flow rate or volume of fluid (such as water) that passes through a hose or pipe based on its diameter, length, and pressure. It aids in various applications, including irrigation, firefighting, and fluid dynamics analysis. The formula for calculating hose flow rate involves considering the hose diameter, length, and pressure.

Formula for calculating hose flow rate:

**Flow Rate = (π * (Hose Diameter)^2 * Pressure) / (4 * Fluid Viscosity * Hose Length)**

In this formula, “π” represents the mathematical constant pi (approximately 3.14159), “Hose Diameter” is the inside diameter of the hose or pipe, “Pressure” is the pressure of the fluid flowing through the hose, “Fluid Viscosity” represents the viscosity of the fluid (a measure of its resistance to flow), and “Hose Length” is the length of the hose or pipe.

For example, let’s say we have a hose with an inside diameter of 0.5 inches, a length of 100 feet, and a fluid pressure of 30 psi. If the fluid viscosity is 1 centipoise (cps), the flow rate would be calculated as follows:

Flow Rate = (π * (0.5 inches)^2 * 30 psi) / (4 * 1 cps * 100 feet) ≈ 0.238 gallons per minute (gpm)

This means that the fluid flow rate through the hose would be approximately 0.238 gallons per minute.

The Hose Flow Rate Calculator simplifies the process of determining fluid flow rates, aiding engineers, firefighters, and other professionals in fluid dynamics analysis and system design. By inputting hose specifications and fluid properties, the calculator quickly provides the estimated flow rate, helping users make informed decisions about hose selection and flow requirements for their applications.
