What is the prime factor of 2662?

11 is one of the factors! The orange divisor(s) above are the prime factors of the number 2,662. If we put all of it together we have the factors 2 x 11 x 11 x 11 = 2,662. It can also be written in exponential form as 21 x 113.

What are the factors of71?

The factors of 71 are 1 and 71. The highest factor of 71 is 71.

What does by a factor of mean?

“by a factor of ” is used commonly to mean the same as “multiplied by” or “divided by.” If x is INCREASED by a factor of 4, it becomes 4x. If x is DECREASED by a factor of 4, it becomes x/4. The key word is the direction of change i.e. (increased / decreased) by a factor of.

What is time factor irrigation?

The time factor is defined as the ratio of actual operating period of a distributary to the crop period. This factor is to check the danger of over-irrigation which can result in water clogging and high salinity.

What is crop factor in irrigation?

The crop water need (ET crop) is defined as the depth (or amount) of water needed to meet the water loss through evapotranspiration. In other words, it is the amount of water needed by the various crops to grow optimally.

How do you calculate an outlet factor?

Comments ( 3 )

  1. Adarsh Tiwari : 9 months ago. The outlet factor is duty of outlet.So here base period and delta are given as 14 and 190 mm.The formula is duty=8.64B/Delta.Delta will be in metre.8.64*1000*14/190=636.7 hectares/cumec.
  2. Bikram Biswas : 1 year ago. the outlet factor is nothing but Duty.
  3. Pawan Jangra : 3 years ago.

What is crop ratio in irrigation?

Crop ratio. It is the ratio of the areas irrigated in Rabi and Kharif seasons. Crop ratio= /frac{Area irrigated during Rabi season}{Area irrigated during Kharif season} Water requirements of Kharif crops is much more than those of rabi crops.

What are the factors affecting duty?


  • Soil characteristics through which canal runs. If canal is unlined and soil through which it flows is coarse grained. Seepage and percolation losses will be too much and duty of water will be reduced.
  • Soil characteristic of fields. If soil of the field is deep coarse grained, percolation losses will be more.

Which crop has highest value of Delta?

Is the heart of drip irrigation system?

Filter: It is the heart of drip irrigation. A filter unit cleans the suspended impurities in the irrigation water so as to prevent blockage of holes and passage of drip nozzles.

What are the two main types of drip irrigation?

In principle, there are two types of drip irrigation: Sub-surface drip irrigation – Water is applied below the soil surface. Surface drip irrigation – Water is applied directly to the soil surface.

What are disadvantages of drip irrigation?

The disadvantages of drip irrigation are: Initial cost can be more than overhead systems. The sun can affect the tubes used for drip irrigation, shortening their lifespan.

Which crop is best for drip irrigation?

Is drip irrigation good for all crops?

By using drip irrigation, farmers can produce higher yields while saving on the water as well as fertilizers, energy, and even crop protection products. Drip irrigation can help reduce evaporation and runoff and contribute to water conservation.

Why is drip irrigation expensive?

Most conventional drip irrigation systems are designed to operate the drippers at a pressure of at least 1 bar. To maintain this pressure requires energy, which constitutes the main capital expense in off-grid drip irrigation systems, and the primary recurring cost in on-grid systems.

Which state has highest area under drip irrigation?

The first place goes to Karnataka (8.16 lakh ha) followed by Andhra Pradesh (7.17 lakh ha) and Gujarat (7 lakh ha).

Which state is least irrigated in India?


What are the 4 types of irrigation?
