Here's my STR silly calculation entry:
We've had a bit of a problem here an our house. Our well pump died Friday, 3/21. Two different well companies tried to pull the pump. It's good and stuck in the well--along with 200+ feet of pipe. What now? Dig a new well because the old one's useless.
So, what's a way to inject some fun into our lives while we're camping at home? Knitting a new well cozy, to be sure! It would have to be done in Mudslide, because that's what my yard looks like now, in lightweight, knit tight enough to keep the clay out but allow water to seep through.
The new well is 250 ft. deep. It's 6 in. in diameter. I knit STR lightweight at 9 stitches to the inch and 13 rows per inch on size 1 needles. How many stitches and rows will I end up with? How many skeins do I need?
Area of a cylinder's sides = 2 * pi * radius * height (in.)
Area of the cylinder's top = pi * r squared
Area of the sides = 2 * 3.1415 * 3 * 3000 = 56,547 sq. in
Area of top = 3.1415 * (3 * 3) = 28.27 sq. in.
So, I need to cover about 56,576 sq. in of surface area. This will protect the new well from bad karma, from cold, from seepage, and from being silted in--the downfall of the old well.
If, in 1 in., I have 9 stitches to the inch and 13 rows using US 1 24" long circular needles, that gives me 9 * 13 or 117 stitches per square inch.
Total number of stitches in my well cozy is 117 * 56,576 or 6,619,392 total stitches.
Total number of rows is height * rows per inch = 3000 * 13 = 39,000, plus the top which I figure to be 39 more rows (13 rows per inch * 3 in. diameter). A grand total of 39,039 rows.
All this seems superfluous, as I haven't yet figured how much yarn I use in a row of stitches. Let me see . . . I need more math just to cast on.
It's 6 inches in diameter, which gives me a radius of 3 in. That does not tell me how far it is around this circle--the circumference. 10th grade geometry, help me!
Circumference is 2 * pi * radius = 2 * 3.1415 * 3 = 18.849
I'll round up to 19 in. for a tiny bit of positive ease. I don't want to work too hard getting this cozy onto the well.
So, with 9 stitches to the inch and 19 in. circumference, I need to cast on 171 stitches. I'll then join in the round and knit in stockinette for 3000 inches. Once at 3000 inches I'll proceed as follows:
Row 39,001: Row *K7, K2tog, repeat from * around.
Row 39,002: Knit even.
Row 39,003: *K6, K2tog, repeat from * around.
Row 39,004: Knit even.
All following odd rows: Continue in pattern decreasing 9 stitches per row. Your decreases should spiral fabulously around the circle.
All following even rows: Knit even.
Stop this pattern when you have 19 stitches left. Cut yarn, leaving about a foot . Draw yarn through all live stitches and pull tight. Attach a clippy thingy. Don't knot, as this will draw the bad karma well gods to your well and they will force a problem that will force you to take the knot out. Leave the live stitches, so you can easily make alterations in the future. You will need to.
In my itty bitty swatch, I used 53 linear inches of yarn for every square inch of stockinette.
I have 56,576 sq. in. to cover, so 53 * 56,576 should give me the length of yarn, in inches, I'll need. That's 2,998,528 linear inches of yarn I'll need. Divided by 12, it's 249,877.3 linear ft.
1 ft. = .333333333 yds., approximately.
That means I'll need about 83,292.433 yards to make my cozy (231.369 skeins). I'll round that up to allow for a little overlap when adding a new ball and a tail to cast on with and a tail to pull at the end, and say I need about 234 skeins of Mudslide in STR Lightweight.
STR lightweight is about 4.5 oz/127 gm. and 360 yds/329 m.
84,240 yds/
That means I need 1053 oz.,29718 gm. and 84,240 yds/76,986 m.
Add two skeins of STR lightweight Blarney Stone to keep my hands and feet warm while knitting the cozy and dressing the well, and all will be grand!
PS, Do you think I should make a hat for the guy out there jamming the pipe into the ground?
