The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
Find the recommended glide speed for maximum range. This glide speed is the speed for L/D max (I'll save you the derivation). This speed also corresponds to the bottom of the drag polar. After all, if lift is a constant for level flight, L/D max will occur at the minimum drag.
If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if your small pulley is 6" diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 500 RPM, Enter Pulley1 Size 6, Pulley 1 RPM 1000, Pulley 2 RPM 500, and hit Calculate to find the second pulley diameter.
Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure. To calculate the speed, consider that abrasive grains on the wheel perimeter traverse the circumference of the wheel once for every revolution of the wheel.
