Diameter=26"
So circumference = pi*diameter=81.8614 inches
2600rev/min=43.333 rev/sec
So in 1 rev = 1/43.333 sec
Speed = distance/time = 81.68 ÷ 1/43.333 = 3539.527 inches/sec = 294.96 ft/sec = 0.055863 miles/sec = 201.1mph.

What is the radius in inches of the wheel A wheel made 3000 revolutions while traveling 45000 pi inches in a stright line along the ground . give answer and explanation?
If the wheel made 3000 revolutions and covered 45000 pi inches, then one revolution would cover 15 pi inches. That is the circumference. The circumference is equal to 2 times the radius times pi. Then the radius is 7.5 inches.
If a rectangle is 3 inches by 5 inches what is its area?
3 inches times 5 inches = 15 square inches
How can you convert inches into square inches?
To convert inches to square inches you need to know 2 different dimensions of an object. The 2 dimensions have to be in inches or converted into inches. Here is an example: The front of an object is 1 foot tall by 8 inches wide, what is the objects area in sq. inches. Solution: Height is 1 foot or 12 inches and the width of the object is 8 inches. 12 inches x 8 inches = 96 sq. inches.

How many revolutions per minute are the wheels of a bicycle turning if the diameter is 26 inches and you are traveling at a speed of 35 miles per hour?
Bicycle wheels with a diameter of 26 inches, travelling 35 miles per hour, are turning 452 revolutions per minute. 35 miles per hour is 36,960 inches per minute (25 *5280 * 12 / 60) 26 inches diameter is 81.7 inches circumference, so the revolutions per minute is 36,960 / 81.7 or 452 revolutions per minute.
What is the trigonometric formula for rotational velocity?
Velocity = Radius x RPM For example if a body of 32 Inches in diameter rotating at 3600 rpm, the velocity is calculated by Velocity = 32/2 * 3600 Velocity = 57,200 inches per minute Velocity = 57,200 Inches/min * 60 Min/Hr * 1ft/12in * 1 mi/5280 ft Velocity = 54.5 miles per hr

The angular velocity in revolutions per second of an 18 inch diameter tire on a vehicle that is traveling at 80 mph?
First, the circumference of an 18 inch wheel is 18 * pi = 56.549 inches. 80 miles per hour is 80 * 5280 * 12 = 5069000 inches per hour. This is 5069000 / 3600 = 1408.06 inches per second. So, 1408.06/56.549 = 24.90 rev per second.

How do you calculate impact Energy for Pneumatic Hammers or how to calculate the Hammer piston velocity?
Hammer piston velocity is: Velocity of an pneumatic cylinder can be calculated as s = 28.8 q / A (1) where s = velocity (inches/sec) q = volume flow (cubic feet/min)A = piston area (square inches) Do you know how to calculate the impact PSI? - This is where I get lost.
