gravity feed calculation help !!!
I have a 1500 gallon water tank 200 feet up the hill (@ 25 feet) in my back yard
I am installing an orchard and garden, as well as additional lines for emergencies for fire protection here in northern california
I am not sure how to calculate the pressure from the tank and how many heads I can use with the gravity feed created (way novice I know).. I need at least three sprinkler heads to cover each 90 foot line??? Or should i use four smaller ones.??
I assume a 1 1/4 to 1 1/2 inch main line running downhill?
Is there any additional advantage to using a 1 inch line instead of the 1/14 inch for each 90 line?
How much pressure is created ?
What type of head and what size line is best for my needs ?
