Channel depth????

[LiquidRulez]

How deep would two 1/8" channels have to be in order to equal a 0.375" inlet??


Thanks

~0.442in

thanks

can you tell me how you deterrmined that for future reference??
thanks again

For a 0.375 opening, the radius is 0.1875.

Following the formula: pi*r^2, the area of such an opening is 0.11 in sq.

two 1/8 channels is 1/4 by X, where X=.11/.25, which equals 0.442 .

area of channel = x * .125 (1/8")
area of inlet = pi * r^2 = 3.1416 * (.1875^2)

It's all algebra from here:

x = (pi * (.1875^2))/(2 * .125) = .11045/.25 = .4418

Hope that helps

Yeah, what he said!

All that's well and good, but don't forget that often times a fitting "size" does not match the true opening size. eg, NPT pipe sizes are "nominal" and never is the inside diameter of NPT equal to the "size". As another example, tubing fittings often have IDs much smaller than the "size". A 3/8" tube to NPT has an ID of only 0.22" on the hose barb end.

Always be certain you know the true diameter of the fittings in use in your system.

This caught me out recently, I was measuring the inner diametre of my pump outlet and it was 3/8inch exactly, I thought it was a 3/8Barb, but it was a 1/2 barb. where's the logic?! . to make it worse it all depends on the manufacturer, they're all different sizes. I'll be using 5/8 barbs/fittings on anything I do myself from now on , specialy equal Y fittings, ect...
