Well I've been looking to build a boat for quite awhile. I'm 14.. I know I can, but my problem is money. I've been looking to build the Bingo but I'm concerned about the trustworthy ness of the site and if I go as cheap as possible while still doing it right, how much money will it cost me? I have a TON of questions, but I'll just leave it at those for now.thanks.
Recently i purchased a new kind of alarm clock which not only beeps when the alarm goes off, but it also has a pad that goes under your matress that vibrates when your alarm goes off. I was just like you, never being able to get up when my old alarm went off, but since i purchased this new alarm clock i have not missed my alarm one time.
In a moving fluid I would have to say yes. Even a frictionless bend must induce turbulence and some energy loss.
The basic equation of pressure drop in straight pipe is Darcy equation. Pr drop in pipe fLv^2/ 2dg However for fittings, the equation becomes Pr drop Kv^2/ 2g K is a pr drop constant for each fitting which is based on the shape and fluid losses due to change in flow patterns and turbulence, even for smooth bend lower K value shall be there for sudden change in fluid flow (turbulent friction factor or resistence coefficient) , which mean obstruction and turbulence loss. so you are absolutey right . there will be loss in a fitting irrespective of friction.
