MCQ Detailed View

The term "Cusec" is a standard scientific term used to express the rate of water flow in rivers, canals, and pipelines. It is a short form for "cubic feet per second" (cu-sec), meaning it measures the volume of water passing a point in one second. This makes cusec a unit of flow rate, combining both volume and time. Definition:

• 
  

  1 cusec = 1 cubic foot of water flowing per second.

  
  


• 
  

  Since 1 cubic foot ≈ 28.317 liters, 1 cusec ≈ 28.3 liters of water per second.

  
  

This unit is commonly used in:

• 
  

  Hydrology – to measure river discharge

  
  


• 
  

  Irrigation engineering – to calculate water supply to agricultural fields

  
  


• 
  

  Dams and reservoir management – to monitor the amount of water released

  
  


• 
  

  Flood control systems – to estimate water flow during heavy rains

  
  

Unlike the given options:

• 
  

  Area is measured in square units (m², ft²)

  
  


• 
  

  Time is measured in seconds, minutes, hours

  
  


• 
  

  Distance is measured in meters, kilometers, feet, etc.

  
  


• 
  

  Mass is measured in kilograms, grams, or pounds

  
  

"Cusec" doesn’t directly represent any of these quantities. Instead, it is a derived unit showing how much water (volume) passes through a cross-section of a river or pipe per second (time).

In international scientific systems (SI units), cubic meters per second (m³/s) is preferred, but "cusec" remains widely used in many regions for water resource management due to its practicality.

✅ Final Answer:

The correct option is None of these, because cusec is specifically a unit of water flow rate, not area, time, distance, or mass.
