Maximum PSI rating is on the outside rating of the pipe
What schedule pipe?
I'm no pool expert but I can do the basic maths. I'd presume the limiting factor on how much water will pass through a pipe is its cross sectional area, and that these are circular pipes. If so, the area of a 1.5 inch diameter pipe is pi x .75 x .75, and of a 2inch diameter pipe is pi x 1 x 1 . So two of the smaller pipes will have a combined area of 1.125pi sq. inches, more than the single bigger pipe at 1pi sq. inches. Two 1.5" pipes into a single 2" line is acceptable for your flow rates. The flow rate will depend more on your pump than the two 1.5" diameter lines. You could add a third, or even more lines and individually isolate them with ball valves so you can adjust the flow from each as per the requirements of the pool.
Flow Max is a filter so I would say no.
An example of a Max Flow Problem is determining the maximum amount of water that can flow through a network of pipes. This problem is typically solved using algorithms like Ford-Fulkerson or Edmonds-Karp, which find the maximum flow by iteratively augmenting the flow along the paths in the network.

Depends on what pipe you are asking about. Most pipe such as PVC has a max heat rating for internal and external temperatures. this is why regular white PVC should never be used for hot water from a hot water heater which can be 120 degrees (F) or more and melt regular PVC. That is why they recommend using CPVC which has a higher temperature rating. Depends on what pipe you are asking about.

Maximum allowable water velocity is generally kept as 3m/sec. But we have seen higher velocities also work.
To increase the pressure you would have to reduce the diameter of the pipe. Half the diameter would give you twice as much pressure. Therefore to get 25 percent more pressure you would reduce the diameter by 25 percent giving you 37.5. Be careful though, this only increases the water pressure not the water flow rate.
Is this pipe going to be threaded / Grooved or Welded?
3" Min - 4" is Max
Max A. Heaslet has written: 'Compressible potential flow with circulation about a circular cylinder'
Depends on pressure and temp end connection ect>
