1. What is the Weight of Water Delivered Formula?

The formula calculates the weight of liquid delivered by a reciprocating pump based on specific weight, piston area, stroke length, and pump speed. It provides the force exerted by the liquid entering/exiting the pump.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Weight of liquid (N)
• \( \gamma \) — Specific weight (N/m³)
• \( A_p \) — Area of piston (m²)
• \( L \) — Length of stroke (m)
• \( N \) — Speed (rpm)

Explanation: The formula calculates the weight of liquid delivered per minute by accounting for the pump's geometric parameters and operating speed.

3. Importance of Weight Calculation

Details: Accurate weight calculation is crucial for pump design, performance evaluation, and system efficiency analysis in fluid handling applications.

4. Using the Calculator

Tips: Enter specific weight in N/m³, piston area in m², stroke length in m, and speed in rpm. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight?
A: Specific weight is the weight per unit volume of a substance, typically measured in N/m³.

Q2: How does piston area affect the result?
A: Larger piston area increases the volume of liquid displaced per stroke, resulting in higher weight delivery.

Q3: Why divide speed by 60?
A: Speed is in revolutions per minute (rpm), so dividing by 60 converts it to revolutions per second for proper unit consistency.

Q4: What types of pumps use this formula?
A: This formula applies to reciprocating pumps where liquid is displaced by a piston moving back and forth in a cylinder.

Q5: Can this be used for other liquids besides water?
A: Yes, by using the appropriate specific weight value for the liquid being pumped.
