Dear Stressedguy,

My objective was not to hurt you as like you I am a professional and I keep out my personal emotions out of my profession.

But being a prefesional you should know :

1) This forum has experienced persons who knows what to take and what not to.

2) Newcomers who have not developed that ability and can accept things on a face value.

3)This is a forum for engineers and SAM in his response has clearly mentioned that engineers do not "feel" but "understand by logic".

For new comers who can take your statements on face value can design systems which can result in catastrophic failures ( I wish you would have seen photographs of failure of pump foundations in case of untied bellows).

Last but not the least , if you have to develop yourself in your profession learn the meaning of the word "humility" and delearn the meaning of the word "ego". There is no end to learning and we everyday learn something from somebody.

Only then you will succeed.

Regards
