1. What is a Hydraulic Cylinder Flow Rate Calculator?

Definition: This calculator determines the volumetric flow rate (Q) of hydraulic fluid through a cylinder based on the cross-sectional area and flow velocity.

Purpose: It helps hydraulic system designers and technicians calculate the required flow rate for proper cylinder operation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Volumetric flow rate (m³/s)
• \( A \) — Cross-sectional area of cylinder (m²)
• \( v \) — Flow velocity of hydraulic fluid (m/s)

Explanation: The flow rate is simply the product of the cylinder's cross-sectional area and the fluid velocity.

3. Importance of Flow Rate Calculation

Details: Proper flow rate calculation ensures correct cylinder speed, adequate pump sizing, and efficient system performance.

4. Using the Calculator

Tips: Enter the cylinder's cross-sectional area in m² and the desired fluid velocity in m/s. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the cross-sectional area?
A: For circular cylinders, use \( A = \pi \times r^2 \) where r is the bore radius.

Q2: What's a typical flow velocity?
A: Common velocities range from 0.3-4.5 m/s, with 1.5-3 m/s being typical for most applications.

Q3: How does this relate to cylinder speed?
A: Cylinder speed = Flow rate / Piston area. This calculator gives you the required flow rate for a given velocity.

Q4: Can I use different units?
A: The calculator uses SI units. For imperial units (gpm, in², ft/s), you'll need to convert the results.

Q5: What affects flow velocity?
A: Pump capacity, hose diameter, system pressure, and fluid viscosity all influence achievable velocity.
