1. What is the Discharge Formula?

The discharge formula calculates the rate of flow of a liquid through a rectangular tank based on its dimensions and detention time. It is commonly used in hydraulic engineering and water treatment processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Width — Horizontal measurement of the tank (m)
• Length — Measurement from end to end of the tank (m)
• Depth — Vertical distance from surface to bottom (m)
• Detention Time — Time water is retained in the tank (s)

Explanation: The formula calculates the volumetric flow rate by dividing the tank volume by the detention time.

3. Importance of Discharge Calculation

Details: Accurate discharge calculation is crucial for designing water treatment systems, managing water resources, and ensuring proper hydraulic performance in various engineering applications.

4. Using the Calculator

Tips: Enter all dimensions in meters and detention time in seconds. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is detention time?
A: Detention time is the theoretical time required for a given amount of water to pass through a tank at a given flow rate.

Q2: Why is discharge important in water treatment?
A: Proper discharge calculation ensures adequate treatment time and efficient operation of water treatment facilities.

Q3: Can this formula be used for non-rectangular tanks?
A: No, this specific formula is designed for rectangular tanks. Different formulas apply for circular or irregular-shaped tanks.

Q4: What are typical units for discharge?
A: Discharge is typically measured in cubic meters per second (m³/s) or liters per second (L/s).

Q5: How does temperature affect discharge calculations?
A: While temperature affects fluid properties like viscosity, this basic volumetric flow calculation assumes constant fluid properties.
