What is meant by Hydraulic smooth pipe?
The original answer is incorrect (at least in the North American meaning of the term 'Hydraulically smooth'. Hydraulically smooth mean that the roughness on the wall of the pipe is less than 1/2 of the thickness of the viscous sublayer of the turbulent flow. The viscous sublayer is (well) less than 1% of the pipe diameter. The viscous sublayer thickness is calculated as: t=5D*(8^0.5)/((f^0/5)*Re where t is the thickness, D is the Diameter, f is the Darcy Friction Factor (found from the Moody Diagram or the Colebrook Equation, and Re is the Reynolds number, based upon pipe diameter and the average flow velocity in the pipe. Re = u*D/v u is average velocity v is kinematic viscosity As a last comment on the old response, it is in fact describing the critical flow rate for transition to turbulence (i.e. the flow rate for Re ~= 2300). The exact value for transition to turbulence is dicey to determine, and does, as the answer says, depend on the roughness and disturbances. Further, as the equation for Reynolds number shows, the transition to turbulence also depends on diameter. Laminar (not turbulent) flow is often called 'smooth', and the study of fluid motion is hydraulics, so it's easy to get the meaning of 'hydraulically smooth', mixed up with 'smooth (laminar) flow' *****Old (incorrect) response***** The flow rate inside a pipe that will produce laminar(No turbulence) flow. The physical smoothness plays a part but need not be as smooth as glass. A concrete, cast iron , copper and glass pipe can all produce laminar flow. The flow rate at which turbulence begins (no longer hydraulically smooth) will depend upon the surface texture where rougher surfaces will cause turbulence to occur at lower flow rates compared to a smoother material. Raise the flow rate enough and your will eventually get turbulence. So to have hydraulically smooth pipes you would need to spec no only the material but diameter as well to ensure laminar flow up to the max expected flow rate. Also any turbulence inducing fittings would also be included. For example a bar grate in a storm water system could be installed such that hydraulically smooth flow is maintained for low flow rates. (The water ca easily pass around the bars). During the high flows a storm would produce the bar grate would cause a restriction and you would no longer have smooth flow.

What is meaning of head of pump?
it is the max vertical height upto which pump can supply the water.
How to calculate head presure of a water tank?
Just measure the elevation of the max water height above the ground (or whatever reference level you wish to use).
Max water flow in 1 inch PVC pipe?
Maximum PSI rating is on the outside rating of the pipe
Max waterflow in 2 inch PVC pipe?
What schedule pipe?
Can flow max get you high?
Flow Max is a filter so I would say no.
What is an example of a Max Flow Problem and how is it typically solved?
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.
What purpose of heat number write on the pipe?
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.

What is max allowable water velocity in steel pipe?
Maximum allowable water velocity is generally kept as 3m/sec. But we have seen higher velocities also work.
You had a shower system that required 2.5 bar pressure to operate however the incoming pressure is only 2 bar max on a Dia50 nominal pipe how can you increase the pressure without pumps?
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.

Will two 1.5-inch PVC pipes into a 2-inch PVC pipe flow as much water as 2-inch PVC into your pool pump and what would be the max gpm the pump could draw and would you need three 1.5-inch pipes?
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.
