Sudden enlargement:
Calculate the D2/D1 ratio from 1-inch
copper tube (type K) to a
3-inch copper tube (type K).
Now read the resistance coefficient K from chart for a velocity
of 12 m/s and 0.6 m/s
E.g. 10.1 in notes: Calculate v1,
(v1)2 /2g, and D2/D1
ratio.
E.g. 10.2 in notes (using information from example 10.1):
Calculate v2, calculate (p1-p2) if
the flow is glycerin instead of water (specific weight glycerin is
12.34 kN/m3 ).
What is the resistance coefficient for a cone angle of
400 with a D2/D1 ratio of 2 for
gradual enlargement?
E.g. 10.6 in notes: For the same problem what is the energy
loss for a square edged pipe?
