spin rate depends on the RPM of the entire device turning it. If both are turning at the same RPM, they both spin the same speed.
Fans can have any number blades--even one! (but then you need a counterweight for balance). There are airplanes that have one blade for a propeller. There are many variables that figure into how many blades a fan has. Air velocity, noise, shape of the blade, length of the blade, material cost, vibration, etc. For airplanes sometimes they change 2-bladed propellers for three or four or more to get different flying characteristics.
A four input and gate is a logic gate with four inputs. The output is true only when all four inputs are true.
•Interleaving works by dividing the system memory into multiple blocks. The most common numbers are two or four, called two-wayor four-way interleaving, respectively. Each block of memory is accessed using different sets of control lines, which are merged together on the memory bus. When a read or write is begun to one block, a read or write to other blocks can be overlapped with the first one. The more blocks, the more that overlapping can be done. As an analogy, consider eating a plate of food with a fork. Two-way interleaving would mean dividing the food onto two plates and eating with both hands, using two forks. (Four-way interleaving would require two more hands. :^) ) Remember that here the processor is doing the "eating" and it is much faster than the forks (memory) "feeding" it (unlike a person, whose hands are generally faster.)
There four p's in software engineering. The four p's are people , product, process, project.
the answer is four.

It is possible to replace one kind of propeller (sometimes called a screw) with another kind. When moving to the "less complex" two blade propeller, the mechanisms that control the pitch of the blades of the propeller with pitch control will be abandoned or removed. There may be a lot more to this, but the basic answer is that you can replace one kind of propeller with another kind, as long as the "handedness" of the screw is the same as the one coming off. Or you'll go backwards in "Ahead" and ahead in "Back" on the direction selector.

Nothing, IF it's made for a four blade fan. If it is a FIVE blade fan and you only have four blades, then it will be out of balance. It doesn't matter how many blades as long as they are spaced out equally and are balanced right.
The most well known airplane with four propeller driven engines on each wing was the "Spruce Goose". It was designed by Howard Hughes and flew only one time for a short distance.
