1. What is the Discharge From Well Given Specific Capacity Formula?

The formula calculates the discharge from a well based on specific capacity, cross-sectional area, and constant depression head. It provides an accurate assessment of water flow rate from wells and is essential for groundwater resource management.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = K_A \times A_{cs} \times H \]

Where:

Explanation: The formula calculates the flow rate by multiplying the specific capacity of the well by its cross-sectional area and the constant depression head.

3. Importance of Discharge Calculation

Details: Accurate discharge calculation is crucial for well design, groundwater resource assessment, irrigation planning, and determining sustainable water extraction rates.

4. Using the Calculator

Tips: Enter specific capacity in m/s, cross-sectional area in m², and constant depression head in m. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is specific capacity in well hydraulics?
A: Specific capacity is a measure of well productivity, defined as the discharge per unit drawdown (Q/s).

Q2: How is cross-sectional area determined for a well?
A: For circular wells, cross-sectional area is calculated as π × (radius)². For rectangular wells, it's length × width.

Q3: What factors affect constant depression head?
A: Depression head is influenced by aquifer characteristics, well construction, pumping rate, and duration of pumping.

Q4: When is this formula most applicable?
A: This formula is particularly useful for steady-state flow conditions in confined and unconfined aquifers.

Q5: Are there limitations to this calculation method?
A: The formula assumes homogeneous aquifer conditions and may need adjustment for complex geological settings or transient flow conditions.
