It depends on the wiring, the current load in the wiring , and the distance. The NEC Code book has the charts for this.And the size of the conduit.

The minimum size you can use is 3/4 conduit. The code allows for a maximum of 4 each # 6 gauge wires in a 3/4 inch pipe. You'll likely be running 3 ea # 6s, two hots and the neutral and a #10 ground wire.
The grounding system of a distribution must be from zero ohms to a maximum of two ohms. This is usually obtained by bonding all metallic parts back to the distribution centre with a wire capable of handling the circuits fault current if the circuit should ground out. The ground wire in cable sets is used for this purpose.
Maximum power rating describes the maximum power at which a device can operate without reaching an excessive temperature. For example, in the case of a resistor, if its maximum power rating is exceeded, then it may burn out.
its 180 degrees If you use the above answer the conduit will flatten and close off. The maximum degrees for a single bend in conduit is 90 degrees. Also code only allows four 90 degree bends in a conduit run between pull boxes.
Adding an extra length of shaft on the existing shaft to take extra pulleys will put an extra load on the bearings supporting the shaft. In the long term this would shorten the life of the bearings. The makers might be able to supply more information like the side-load specification for the bearings. If in doubt support the outer end of the shaft.
This is one of those questions that has a lot of answers! In a residence I would want it as short as possible, however you can legally run it 10 feet, if you use steel flex or metallic liquid tite in your raceway system the maximum length of the flex can only be 6 feet with the remaining 4 feet of conduit. Inspectors in some areas like for the service panel located in the first stud bay available nearest the service entrance, this usually keeps the conduit and wire length to a minimum.
All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.

PVC conduit is recommended for underground installations. Just remember that a ground wire equal to the maximum load current of the device connected at the other end has to be installed. This ground wire is not counted in conduit fill calculations. It has to have a green insulation in colour and be of a continuous length.
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.

That depends on the size of the conductor and the type, which is defined by its insulation. With many common large feeder conductors such as THHW, the largest conductor which you can run 8 of is # 2 gauge. Whereas common small branch circuit conductors such as # 12 THHN, you can run 138 ea. through a 2 " conduit. For the complete list, look at the chart titled "Maximum number of conductors in electrical metallic tubing" (EMT) in the National Electrical Code.
In the United States, the National Electric Code dictates the depth of buried electrical lines. You have not provided enough info for me to give an accurate answer. For instance, some cables are manufactured for direct burial, that is to say without a conduit. Other considerations would be whether or not you are crossing a driveway, or alleyway. However, the maximum depth required is 24 inches to the top of the conduit or cable. Under certain conditions this depth may be reduced to 18 inches to the top of the conduit. Thank you for your desire to make a good installation.
