head loss
loss due to sudden enlargement
we can improve the bernoulli equation by adding the head losses at the final flow state and also we account the major (friction loss and viscus loss) losses and Minor losses (pipe bend , pipe contraction , pipe inlet and outlet, pipe fittings , valves etc)... If we account those losses and added to the head losses then the Bernoulli's equation gives the very accurate value....
Relative roughness is a measure of the surface roughness of pipe surfaces. It is the size of the roughness scaled by the diameter of the pipe or duct. Rel Roughness=e/D; where e is the measurement of the surface roughness and D is the diameter of the pipe. It is mainly used for calculating head losses in piping systems.
Seamless pipe is very expensive, and is only used in certain applications, such as steam condensate return, where ERW (seamed) pipe would not last as long. For a handrail, go with the ERW.

Increase the pressure.'ABSOLUTELY WRONG.Pressure cannot be increase by reducing a pipe diameter.If you have 60 PSI Flowing thought 2" pipe and decrease the pipe to 1" you still have the same 60 PSI supply pressure.If the above lie was true then why not have the city main be 60" pipe reduce it to 2" to give "pressure" to 47 high rises?What is actually happening your INCREASING VELOCITY LOWERING Volume and doing NOTHING but possibly lowering the pressures do to friction losses
The major losses within a pipe are those that occur through out the lenght of the pipe, they are caused by the interaction of the water particles and the inner surface of the pipe as water flows through it. Now minor losses are those that occur due to fitting and connections in a pipe sytem, such as 90 degree bends or turns, or valves, etc. These cause minor losses. Major losses are more significant than minor losses.

Bend meter is a type of pipe which are bend may be sharply or 90 degree . In fluid mechanics we calculate the losses inside the pipe .in which losses are more.

types of magnetic losses
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
Losses due to the local disturbances of the flow in the conduits such as changes incross section, projecting gaskets, elbows, valves and similar items are called minorlosses. In other words, the losses that occur in pipelines due to bends, elbows, joints, valves, etc. are sometimes called minor losses.In case of a very long pipe, these losses are usually insignificant incomparison to the fluid friction in the length considered. But In case of short pipes,these minor losses may actually be major losses such as in suction pipe of a pumpwith strainer and foot valves.
Male Iron Pipe Adapter. This means it has male pipe threads and will adapt to either PVC pipe, Poly pipe or a few other types of pipe to make a transition from threaded pipe to something else.
To help figure out correct pipe size needed.
There is a glue specifically for gray pipe. I believe there are glues sold these days that are capable of glueing several different types of pipe.
I think there are two types of stove pipes. 1) Double Wall Stove Pipe 2) Single Wall Stove Pipe
