1. What is a Flow Rate Calculator Cytiva?

Definition: This calculator estimates the flow rate in gallons per minute (GPM) for Cytiva systems based on velocity and cross-sectional area.

Purpose: It helps bioprocessing professionals determine flow rates in fluid systems for optimal process design and operation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Flow rate (gallons per minute)
• \( V \) — Velocity (feet per second)
• \( A \) — Cross-sectional area (square feet)
• 448.83 — Conversion factor (ft³/s to GPM)

Explanation: The velocity is multiplied by the cross-sectional area to get volumetric flow in ft³/s, then converted to GPM.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate estimation ensures proper system sizing, process efficiency, and meets bioprocessing requirements.

4. Using the Calculator

Tips: Enter the fluid velocity in ft/s and the pipe/channel cross-sectional area in ft². All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 448.83?
A: This converts cubic feet per second to gallons per minute (1 ft³/s = 448.83 GPM).

Q2: What's a typical velocity range for bioprocessing?
A: Typically 1-5 ft/s, but depends on the specific process requirements.

Q3: How do I calculate cross-sectional area?
A: For circular pipes: \( A = \pi \times r^2 \), where r is the radius in feet.

Q4: Does this work for non-Newtonian fluids?
A: This calculation is for Newtonian fluids. Non-Newtonian fluids require more complex calculations.

Q5: What about pressure drop considerations?
A: This calculator provides flow rate only. Pressure drop calculations require additional parameters.
