Answer:
Throat diameter
=28.60 mm
Explanation:
Bore diameter
⇒
Manometric deflection x=235 mm
Flow rate Q=240 Lt/min⇒ Q=.004
Coefficient of discharge
=0.8
We know that discharge through venturi meter


=13.6 for Hg and
=1 for water.

h=2.961 m
Now by putting the all value in



⇒
=28.60 mm
So throat diameter
=28.60 mm
Explanation:
For true Strain:
step 1:
E true = Ln(1 + 0.5 ) = 0.40
Step 2:
E true = Ln(1 + 0.33 ) = 0.29
By single step process:
E true = Ln(1 + 1 ) = 0.69
total strain of step process = 0.40 + 0.29 = 0.69 units
SO TRUE STRAIN IS ADDITIVE.
