Real-Life Math -- Solution
You're a sales engineer working for an irrigation company. You're
hoping to make a sale to a company that has come up with a new type of corn
seed. Before you put together a proposal for the client, you need to figure
out a few details of the system requirements.
For a 60-acre plot, you
need to apply 1 inch of water every 3 days for 15 hours a day. What is the
flow rate of water you will need for this system?
This is the formula
you will need to use to calculate flow rate:
Q = (453 x A x D) / (F
x H)
Q = Flow rate (gallons per minute)
A = Total area irrigated
(acres)
D = Depth of water applied (inches)
F = Irrigation frequency
(days)
H = Hours of operation per day
These are your numbers:
Q
= flow rate
A = 60 acres
D = 1 inch
F = 3 days
H = 15 hours
Put
these numbers into the formula:
Q = (453 x 60 acres x 1 inch) / (3 days
x 15 hours)
Q = 604 gallons per minute
The flow rate of water you
will need for the system is 604 gallons per minute.
