1. What is Volume of Liquid Delivered in One Revolution?

The volume of liquid delivered in one revolution of the crank in a double-acting reciprocating pump represents the total fluid displacement per complete cycle of the pump mechanism.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Volume of liquid delivered (m³)
• \( L \) — Length of stroke (m)
• \( dp \) — Piston diameter (m)
• \( d \) — Diameter of piston rod (m)
• \( \pi \) — Mathematical constant pi (approximately 3.14159)

Explanation: This formula accounts for the double-acting nature of the pump where fluid is displaced during both forward and return strokes.

3. Importance of Volume Calculation

Details: Accurate volume calculation is essential for pump sizing, system design, flow rate determination, and performance evaluation in hydraulic systems and fluid transfer applications.

4. Using the Calculator

Tips: Enter all dimensions in meters. Ensure piston diameter is greater than piston rod diameter for valid results. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a double-acting reciprocating pump?
A: A pump that delivers fluid during both the forward and return strokes of the piston, providing more continuous flow compared to single-acting pumps.

Q2: Why is the piston rod diameter subtracted in the formula?
A: The piston rod occupies space on one side of the piston, reducing the effective displacement area during the return stroke.

Q3: What are typical applications of double-acting reciprocating pumps?
A: High-pressure applications, hydraulic systems, water jet cutting, and processes requiring steady fluid delivery.

Q4: How does stroke length affect the volume delivered?
A: Volume is directly proportional to stroke length - longer strokes result in greater fluid displacement per revolution.

Q5: What units should be used for input values?
A: All linear dimensions should be in meters (m) for consistent volume results in cubic meters (m³).
