Flow Rate Formula:
From: | To: |
Definition: This calculator determines the flow rate required for a hydraulic cylinder based on piston area and velocity.
Purpose: It helps hydraulic system designers and technicians calculate the necessary flow rate to achieve desired cylinder movement.
The calculator uses the formula:
Where:
Explanation: The flow rate equals the cross-sectional area of the piston multiplied by its velocity.
Details: Proper flow rate calculation ensures correct hydraulic pump sizing, proper cylinder speed, and efficient system operation.
Tips: Enter the piston area in square meters and desired piston velocity in meters per second. All values must be > 0.
Q1: How do I calculate piston area?
A: For circular pistons, use \( A = \pi \times r^2 \) where r is the piston radius.
Q2: What's a typical piston velocity?
A: Industrial hydraulic cylinders typically operate at 0.1-0.5 m/s, but this varies by application.
Q3: How do I convert m³/s to L/min?
A: Multiply m³/s by 60000 to get L/min (1 m³/s = 60000 L/min).
Q4: Does this account for system losses?
A: No, consider adding 10-20% to the calculated flow rate for system inefficiencies.
Q5: What if I have a double-acting cylinder?
A: Calculate flow rate separately for extension and retraction (different piston areas due to rod).
