For drainage purposes, the current building codes require a minimum two percent slope or a one-fourth unit vertical for every 12 units horizontal. In other words, the roof must slope one-fourth of an inch for every 12 inches. The slope is barely noticeable to the naked eye.
How do you map a green in golf?
Mapping greens is fairly simple. Just sketch the outline shape of the green, rough in the outlines of the 2-4 “flat areas”, then mark the direction of tilt of each flat area (fall line) plus the steepness of tilt (slope percentage) — an arrow for fall line and a number for slope percent.
What is the minimum slope per foot on a flat roof?
1/4 inch per foot

How much slope do you need for water to drain?
The standard slope for proper concrete drainage is a one-quarter inch drop for every foot of length.
How do you write slope on a roof?
If the rise is 6 inches for every 12 inches of run, then the roof slope is “6 in 12.” The slope can be expressed numerically as a ratio. The slope ratio represents a certain amount of vertical rise for every 12 inches of horizontal run. For example, a “4 in 12” slope can be expressed as the ratio of 4:12.
How do you read golf greens for speed and break?
- Step 1 Find the straight putt.
- Step 2 Gauge the slope of the green.
- Step 3 View the green from around the hole.
- Step 4 View the green from where you are going to hit the ball.
- Step 5 Visualize the path of the ball.
How do you explain pitch on a roof?
Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
How are golf greens measured for speed?
It is basically just a small ramp down which golf balls are rolled. A golf course's superintendent or tournament officials measure green speed by rolling balls down the Stimpmeter onto a flat part of a green. If a ball rolls 11 feet after leaving the ramp, that green is stimping at 11.Jan 1, 2019

What does a 9/12 roof pitch mean?
If a roof rises 9″ in a length of 12″, this is 9/12 roof pitch. 9/12 roof pitch angle = 36.37 degrees.
How do you survey a golf green?
- Have an inviting opening message.
- Begin with simple questions.
- Don't ask intrusive demographic questions.
- Avoid double-barrelled questions.
- Use simple rating systems.
- Avoid introducing bias.
- Don't make the survey too long.
- Keep it anonymous.
What is the average speed of a golf green?
What is the average green speed? The average pace is usually around 9 for the average putting green on most municipal golf courses and 11 or above for PGA Tour events. Golf courses in the United States tend to have faster greens than ones in Europe due to the type of grass and typical weather conditions.
What is a 1212 pitch roof?
In this pitch, the first twelve is your roof's rise and the second twelve is the roof's run. The roof's incline increases 12 feet for every 12 feet of horizontal measurement.

How do you draw a golf shot?
- Set up so that the club face is aiming slightly to the right of your target.
- Aim your feet, hips and shoulders further to the right than the club face (this will, in effect, give the club face a closed position in relation to the swing path, imparting draw spin on the golf ball).
