At least you know that a Newton is a unit of Force, whereas a Pound can be Force or Mass and you then need Slugs or Poundals for the other unit. What a mess! The great thing about the SI system is its consistency, although you do end up with some unhelpful scaling. PS I was taught both imperial and CGS units at school in the dim and distant past and have no regrets having mainly left them behind (especially CGS - abamps & statvolts, anyone?). However, when cutting timber I use whatever measurements are closest to the divisions on a tape measure.

2, 3,7, 4&5, 6&8&20 did most things! You are not the only one!

Hagen-Poiseuille is indeed intended for laminar flow, but D'Arcy-Weisbach (or Hazen-Williams) will give a "similar" 1/r^4 relationship for pressure drop vs, pipe diameter for turbulent flow. The flow is likely to be turbulent (5 lpm in a 22mm pipe has a Reynolds Number of about 5,000). Chris G

I have always used foam core board (the stuff with a plastic, not paper face!), with low friction plastic strips glued to it for runners. It is basically unaffected by water and can be wiped clean. Also, it is a sufficiently poor conductor of heat to more or less eliminate condensation. Chris G

Always makes it worse would be my experience! It is the sheer unpredictability of galling which I find so frustrating - you can assemble dozens of SS nuts and bolts without any problem and then suddenly one will start galling and lock up solid. Its isn't as if it is related surface roughness - I have had a ground stainless tube which was supposed to slide in a ground stainless housing (a bad design) suddenly lock up, with eventual separation only achieved using a sledgehammer!

Spot the red flags, AKA don't buy that boat you fool
Batavia replied to admiralhaddock's topic in New to Boating?
It is a long time since I heard someone mention the Six Foot Rule - I think that it last appeared in the 14th Edition! -
A sale has now been agreed.

That is one of the weakest excuses I have ever heard! Chris G.

Just to bring attention to my recent post in the For Sale section of the Forum! Chris G

I remember buying 12 bit Burr-Brown ADCs, with a conversion time of 3.5 uSec, for about £200 each in 1975!

A man of many talents! In my case I was fortunate that this wasn't a pre-requisite for being able to solve Maxwell's equations numerically!
