Irrigation Principle & Design (see attachments)

[Atomicquill]

This was an assignment last week & as I'm not looking for the answers what I am hoping is that similar problems could be shown & the method(s)/work used to arrive at the answer(s) as I'll be encountering these problems in the future as a Farmer. Mahalo for your time & consideration.

ps ET stands for (Evapotranspiration)

Homework (9/11):

I. ET = 0.2" - (per day)
Area = 5,000 sq ft
Water = 4 - (hours daily)
* Find GPM (gallons per minute)
** An Acre is 43,560 ft^2

II. Drip Tree Spacing - 16" x 18"
(4) Emitters per tree
(1) GPH (gallons per hour) per emitter
(10) Acres
(8) Hours irrigation
* Find inches per day

I. ET = 0.2" - (per day)

What is the "per day" that you're subtracting from the two-tenths of an inch? What is meant by the two-tenths of an inch (since water volume would usually be, well, a volume, thus cubic, rather than the linear measure provided)?

Area = 5,000 sq ft

"Area" of what? How does this relate?

Water = 4 - (hours daily)

What is the "hours daily" that you're subtracting from the "4"? What does the "4" stand for? What does "Water" mean? How does this relate?

* Find GPM (gallons per minute)

"Find gallons per minute" for what?

II. Drip Tree Spacing - 16" x 18"

How is this information to be used?

(4) Emitters per tree
(1) GPH (gallons per hour) per emitter
(10) Acres
(8) Hours irrigation
* Find inches per day

How many tree-spaces are in one acre? (Remember to include the boundaries, if they are in fact included. Otherwise, make other adjustments.)

Then how many total tree-spaces are there?

Then how many emitters are there?

Then how many gallons per hour are emitted?

Then how many gallons are emitted in one day?

Then how many cubic feet are emitted in one day?

How many square feet are in ten acres?

Then how many feet in depth are emitted?

Then how many inches in depth are emitted?

If you get stuck, please reply showing your answers to the above. Thank you!
