How much difference does heat make on golf balls?
The warmer balls spun a tick more on average and flew just a bit lower. The average carry difference was only one yard. In the extreme, it’s likely that leaving your bag in the trunk of your car all day would have a greater impact. That’s based on what happened when we placed balls under a heat lamp.
How much does temperature affect a golf ball’s carry change?
Here’s how it breaks down, according to Rice’s recent study, which used a Trackman to test a ball flying 155 mph. As you can see courtesy of the chart above, the carry change increases by about half a yard between your pitching wedge and driver, capping out at about two yards per 10 degrees of temperature.
What is the typical heat capacity of water in joules?
In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/ (kg·K). This is the typical heat capacity of water.

High temperatures will affect the covers of golf balls which in many cases are made of an ionomer which is a thermoplastic which starts melting and deforming at temperatures above about 170 Degrees F.
What does heat do to a golf ball?
Generally, a warmer golf ball travels farther. The rubber materials used to make golf balls respond better if they are more resilient. Warmth enhances resiliency. A warmer ball will come off the clubface with more velocity and spin than a colder ball, encouraging loft.
What is the drag coefficient of a golf ball?
An average golf ball will have a drag coefficient of, 0.24 < CD < 0.7, in a Reynolds number range of 30,000 < ReD < 108,000.
What is the volume of a golf ball?
I calculate the volume of a golf ball to be about 2.5 cubic inches (4/3 * pi * . 85) as . 85 inches is the radius of a golf ball. Divide that 2.5 cubic inches into 1.6 million and you come up with 660,000 golf balls.
Can you heat a golf ball?
Put the golf balls in the hot water on top of the towel. The towel keeps the balls from touching the hot metal on the bottom of the pan. Increase the heat until the water reaches 120 F and remains there. Leave the balls in the water for 30 minutes.

What is the Magnus coefficient of a golf ball?
The golf ball with circular dimples had the least severe reverse Magnus effect, CL = − 0.1, while the ball with hexagonal dimples had the greatest, CL = − 0.15. The magnitude of the reverse Magnus effect was related to the drag crisis of each ball model.
What is the Reynolds number of a golf ball?
The Reynolds number is around 1e5. Comparison of the turbulent wake behind a dimpled golf ball (top), which originates from a turbulent boundary layer separation, and a smooth ball (bottom), which originates from a laminar boundary layer separation.
How is drag calculated?
The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A. For given air conditions, shape, and inclination of the object, we must determine a value for Cd to determine drag.
How do you calculate volume?
To find the volume of a box, simply multiply length, width, and height — and you're good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.

Are large golf balls legal?
Turns out there isn't a rule on how LARGE a golf ball can be, there is only a rule about how SMALL it can be - so as long as a golf ball is at least 1.68 inches in diameter, it is legal.
How does temperature affect golf ball flight?
Generally, temperature affects a ball's resiliency, the spin and the density of the air through which the ball travels.
How does temperature affect a ball's resiliency?
Generally, temperature affects a ball's resiliency, the spin and the density of the air through which the ball travels. Each contributes to how a ball performs. Knowing this can help your scores.
Why are rubber golf balls better?
The rubber materials used to make golf balls respond better if they are more resilient. Warmth enhances resiliency. A warmer ball will come off the clubface with more velocity and spin than a colder ball, encouraging loft. The ball's temperature also has an effect on bounce.
How far can you hit an 8 iron in 50 degrees?
So, if you hit a ball with an 8-iron about 130-yards when it's 90 degrees, you're going to hit it about 122 yards when it's 50 degrees. That's about a club shorter. In colder weather, you may need a 7-iron to hit the ball as far as you might with an 8-iron in warmer conditions.
How many yards does an 8 iron hit?
For every 10 degrees chillier, calculate about 2 yards of lost distance. So, if you hit a ball with an 8-iron about 130-yards when it's 90 degrees, you're going to hit it about 122 yards ...
Can you put golf balls in the microwave?
Some are plug-in units that electronically produce heat that transfers to the ball. Others are compartmentalized units that allow you to put golf balls in the microwave oven.
Warm Balls
We wanted to find out what impact leaving a ball to bake in the sun has on performance. Think of it as what might happen to your golf ball while it’s resting in the fairway while the group in front of you is putting on a slow-play exhibition.
The Takeaway
The initial results of our temperature experiments are interesting and there are definitely a number of rabbit holes we could dive into in pursuit of more insights.
How many yards can a driver carry in 70 degree conditions?
So, if your driver carries about 250 yards in 70-degree conditions, according to Rice’s research, the same shot will travel about 254 yards in 90-degree conditions, and 246 yards in 50-degree conditions. Altitude, as you can see above, is the other big factor. With a driver, you get an extra 2.5 yards per 1,000 feet of altitude.
Does humidity affect golf ball carry?
Rice also found that humidity had “almost no effect on carry,” — temperature and carry were the two primary atmospheric conditions (outside of wind, which is a different matter) that effect your golf ball. So, if your driver carries about 250 yards in 70-degree conditions, according to Rice’s research, the same shot will travel about 254 yards in ...
How to calculate specific heat capacity?
Find the initial and final temperature as well as the mass of the sample and energy supplied.
What is specific heat capacity at constant volume?
The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m).
