As a matter of principle, pipes should be as wide as possible and as short as possible. The larger the diameter and the shorter the pipe, the lower the transmission resistance the pump has to overcome. This applies to both suction and pressure sides.
A diameter of ¾" is adequate for the suction side. If pipes are more than 10 m long, a 1” diameter pipe should be used. The maximum length should not exceed 50 m (pay attention to suction depth).
On the pressure side, we recommend that main pipes with a ¾" in diameter and secondary pipes with a ½" diameter. For a pipe length of 50 metres, a ¾" diameter pipe should be used. If pipe lengths exceed 200 m performance is noticeably reduced due to transmission resistance.
We recommend a diameter of at least 1". More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
