Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball’s surface. This allows the smoothly flowing air to follow the ball’s surface a little farther around the back side of the ball, thereby decreasing the size of the wake.
Are more dimples on a golf ball better?
More dimples being on a golf ball are not necessarily better. The number of dimples that are on a golf ball is less important than the dimensions of the dimples themselves. Too many dimples mean more drag, and too few dimples mean an unpredictable flight trajectory.
Why are there 336 dimples on a golf ball?
Dimples create the aerodynamic ability to hit golf balls for distance. A ball without dimples would not travel very far. The decision to experiment with dimples on golf balls grew out of the discovery that dented or chipped balls actually flew farther and straighter than smooth ones.
Why do golf ball dimples reduce drag?
First, dimples allow air to flow more smoothly around a ball’s surface, which decreases the wake and low-pressure area behind the ball, resulting in less drag. Second, the dimples increase lift by causing the air to move faster at the top of the ball, creating lower pressure there.
Do all golf balls have the same amount of dimples?
The truth is, there is not a single answer to how many dimples are on a golf ball. That’s because the number of dimples varies depending on the model and manufacturer. Most often, the number of dimples per golf ball falls between 300 and 500.
How many dimples are allowed on a golf ball?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch. The lift and drag forces on a golf ball are very sensitive to dimple depth: a depth change of 0.001 inch can produce a radical change to the ball’s trajectory and the overall distance it can fly.
How far would a golf ball go without dimples?
According to Frank Thomas, Golf Digest’s chief technical advisor and former technical director of the USGA, a smooth golf ball with no dimples would travel about 130 yards when hit with a modern driver by a tour-caliber player.
Why are golf ball dimples different sizes?
The dimples work to break the air around the ball in flight, and have two key characteristics that are measured: Lift and Drag. The ideal dimple design is a combination balancing the lift and drag of the ball. We vary the diameters, shapes, total coverage, edge angles to control these two key variables.
How many dimples does a Pro V1 golf ball have?
As for its predecessor Pro V1 (how many dimples are on a Titleist Pro V1 golf ball), it has 352 dimples.
What are the divots in golf balls called?
This is called the Magnus effect. The dimples on a golf ball deform the air around the ball quickly causing a turbulent airflow that results in more Magnus lift than a smooth ball would experience.
Does adding dimples to a car increase its gas mileage MythBusters?
On a recent episode of the TV show MythBusters, special effects experts Adam Savage and Jamie Hyneman ran tests to see if a dirty car is more fuel efficient than a clean one. At constant 65 mph speed, the cleaner car gave 26 MPG and the dimpled one gave an amazing 29 MPG.
What ball has 336 dimples?
On American golf balls, there are usually 336 dimples, while there are 330 on a British ball. However these numbers can vary widely. Golf balls have anywhere from 300-500 dimples. Golf ball manufacturers will manipulate the number, shape, size, and even edge angles to optimize ball flight and trajectory.
How many temples are there in a golf ball?
The dimples are usually the same size as one another, but some golf balls have several different sizes of dimple on the same ball. Any number between 300 and 500 dimples is reasonable, and 336 is a common number.
How long do unused golf balls last?
If unused golf balls are stored at room temperature which is around 70-80 degrees Fahrenheit, they can last for 10 years. Golfweek.com indicates that you wouldn’t be able to tell the difference between a new ball off the shelf and a new one that has been stored for years.
