Why is Pump discharge line size smaller than suction line size?
An increase in any pipe diameter will lower the flow velocity, and therefore reduce head loss due to friction, but it is not immediately obvious to me why pump manufacturers provide a discharge side of smaller diameter than the suction side. I don't think it has anything to do with cavitation, maybe it is just to ensure that fluid flows easily away from the pump, since it will be travelling at a higher velocity in the discharge line than entering the pump on the suction side. Maybe the NPSHR values are derived from the difference in pipe diamters across the pump by the manufacturers, such that cavitation does become an (indirect) issue. Maybe somebody else can answer this one. The suction side of the pump normally has only atmospheric pressure of approximately 1 bar available to propel the oil into the pump. Using a larger suction diameter reduces friction loss, and keeps the fluid as close to atmospheric pressure as possible. Fluids will boil at a lower temperature when subjected to vacuum, and hydrauic systems already have a high temperature due to friction losses elsewhere in the circuit. If the suction side is allowed to develop too much vacuum, the lowered boiling point will be exceeded, and cavitation that is destructive to the pump will be induced. The problem can be alleviated by pressurising or elevating the oil tank to maintain a positive pressure at the pump inlet.
What is a nominal bore size?
Diameter drill is drilling.
Do you have to run suction line the same size from coil to to condenser?
Proper pipe sizing is in the installation manual. The piping should be one continuous run of the same size.
What is the maximum horizontal distance allowed in suction line of a pump which is above the water level?
The maximum distance will be relative to the efficiency of the pump and the rated flow of the pump vs the size of the suction hose. The more efficient the pump, the more vacuum it can draw, and the larger the suction hose in relation to the flow rating of the pump the farther you can move the pump away from the water. The manufacturer of the pump will have charts that will help you properly size and set up your pump for optimum performance.
How do you find the bearing number of a ball bearing?
The bearing number can be checked out depends on the size of ID (Inner Diameter), OD (Outer Diameter) and H (Height) of this bearing.

Why is the suction line of a pump larger than the discharge line?
It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.
Swimming pool suction is too strong?
Doesn't really sound like a question. But your swimming pool suction is determined by the size of your pump. There are other factors like the pipe distance and diameter, but it basically comes down to the size of your pump.

Why do I get Discharge when my breasts are very little developed?
Discharge is linked to puberty and not breast size. Discharge is what cleans the vagina.
