1. What is Time Factor in Irrigation?

Time factor in irrigation is the ratio of the number of days the canal has actually run to the number of days of irrigation period. It represents the operational efficiency of the irrigation system.

2. How Does the Calculator Work?

The calculator uses the Time Factor equation:

Where:

• \( T \) — Time factor in irrigation
• \( Q_{continuous} \) — Continuous discharge required for canal (m³/s)
• \( Q° \) — Discharge required at outlet (m³/s)

Explanation: The equation calculates the operational efficiency ratio by comparing the continuous canal discharge requirement with the outlet discharge requirement.

3. Importance of Time Factor Calculation

Details: Accurate time factor calculation is crucial for irrigation system planning, water resource management, and determining the operational efficiency of irrigation canals.

4. Using the Calculator

Tips: Enter continuous discharge required for canal and discharge required at outlet in m³/s. Both values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What does a time factor greater than 1 indicate?
A: A time factor greater than 1 indicates that the continuous discharge requirement exceeds the outlet discharge, suggesting potential inefficiencies in the irrigation system.

Q2: What is the ideal time factor value?
A: The ideal time factor is typically close to 1, indicating balanced discharge requirements between the canal and outlet.

Q3: How does time factor affect irrigation scheduling?
A: Time factor helps determine the actual operating days needed to meet irrigation requirements and optimize water distribution.

Q4: Can time factor be less than 1?
A: Yes, a time factor less than 1 indicates that the outlet discharge exceeds the continuous canal discharge requirement.

Q5: How is time factor used in irrigation system design?
A: Time factor is used to size canals, determine water allocation, and plan irrigation schedules for optimal water utilization.
