1. What is SCFM to PPH Conversion?

The SCFM to PPH conversion calculates the mass flow rate (pounds per hour) from volumetric flow rate (standard cubic feet per minute) using the material's density. This is commonly used in engineering and industrial applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( SCFM \) — Standard cubic feet per minute
• \( Density \) — Material density in pounds per cubic foot (lb/ft³)
• 60 — Conversion factor (minutes to hours)

Explanation: The formula converts volumetric flow to mass flow by accounting for the material's density and converting the time unit from minutes to hours.

3. Importance of the Conversion

Details: This conversion is essential for process engineering, combustion calculations, and any application where you need to know mass flow rate but only have volumetric flow measurements.

4. Using the Calculator

Tips: Enter SCFM value (must be > 0) and material density (must be > 0). The calculator will compute the mass flow rate in pounds per hour.

5. Frequently Asked Questions (FAQ)

Q1: What is standard condition for SCFM?
A: Standard conditions are typically 68°F (20°C) and 14.7 psia (1 atm), but check your specific application as standards may vary.

Q2: How do I find the density of my material?
A: Material density can be found in engineering handbooks, material safety data sheets (MSDS), or through laboratory measurement.

Q3: Can I use this for gases and liquids?
A: Primarily designed for gases, but can work for liquids if using correct density values. Note that SCFM is typically a gas measurement.

Q4: Why multiply by 60?
A: The factor converts minutes (in SCFM) to hours (in PPH) since there are 60 minutes in an hour.

Q5: What if my density is in other units?
A: Convert your density to lb/ft³ before using this calculator. Common conversions: 1 g/cm³ = 62.43 lb/ft³; 1 kg/m³ = 0.0624 lb/ft³.
