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.
What happens when you remove the dimples from a golf ball?
Four pros found out. Alter the depth of a dimple by as little as 1,000th of an inch and you could negatively affect the ball’s aerodynamics (lift and drag) while it’s rocketing through the air. In this case, the line between success and failure is razor-thin.
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.
What do more dimples on a golf ball mean?
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.
When did golf balls get dimples?
Over time, however, they began to notice that scuffed, scratched and dented gutta-perchas covered a greater distance than smooth ones. Like many inventions, the golf ball dimple was discovered accidentally. By 1930, the dimpled golf ball had become the standard in golfing.
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.
Who designed dimples on golf ball?
In the early 1900s, another inventor found that indentations in golf balls performed far better than raised protrusions. In 1905, an English manufacturer named William Taylor registered a patent for a golf ball dimple design. Before long, all golf balls featured dimples that would be more or less recognizable today.
How many dimples does a Pro V1 have?
Then there’s Titleist Pro V1, one of the best beginner golf balls, with 352 dimples. So it’s unmistakable that dimples differ on golf balls from one brand to another. And not only the number of dimples, but also the shape, size (in a way), and more.
How many dimples does average golf ball have?
Most golf balls have between 300 and 500 dimples, which have an average depth of about 0.010 inch.
What is the optimal number of dimples on a golf ball?
The number of golf ball dimples is less important than the shape and depth of the dimples. The number of dimples can affect drag, so it is important to not have too many dimples. Between 330 and 400 dimples is the optimum number. More dimples mean more focussed control over the ball trajectory.
Why do cars not have dimples in golf balls?
The dimples in a golf ball promote an earlier transition to turbulent flow and thus reduce the pressure drag of the golf ball, so it can fly further. In a car, the size is large enough to develop a turbulent boundary layer early on. Dimples would not help, but increase drag slightly.
What are the dents in golf balls called?
There are no rules about how many dimples a golf ball has to have. Most have 300 to 500 dimples. The most common number of dimples is 392. It was once thought that the more dimples a ball had, the further it would travel.
How many golf balls are on the moon?
There are two golf balls on the moon. They were taken there by Alan Shepard in 1971, during the Apollo 14 mission. Shepard was the first American into space, and the fifth person to ever walk on the moon… but most impressively, he was the first (and only) person to ever play golf outside of the earth’s atmosphere!
What is the liquid inside a golf ball?
Contrary to golf folklore, the liquid cores aren’t dangerous. Titleist, for example, has used a salt water and corn syrup blend. Today’s core is generally made from synthetic rubber — which may be mixed with bits of metal, such as tungsten or titanium — or a plastic-like material such as acrylate.
Are old golf balls worth money?
Because of the age and the craftsmanship put into these balls they are among the ones that have the highest price tag of collectible golf balls. These balls are referred to as antique, and goes for sums upwards of +$5000!
