Equivalent Length

[Mondolfi]

Hi,

I´m looking for Equivalent Length factor (L/D) for a standard pipe enlargement (lets say 30º angle). Although I’ve found this values for elbows and tee’s at CRANE’s, enlargements (and other fittings) usually depends of a K factor, involving density, velocity, etc. Any suggestion for a quick estimation?

Thanks, `
