Answer: True
Explanation:
The total opposition to current flow in an AC circuit is known as Impedance.
Answer: d)Coercion
Explanation:Tool wear is defined as the situation when the cutting tool is subjected to the regular process of cutting metal then they tend to wear because of the continuous action of cutting and facing stresses and pressure . The mechanism that does not happen during this process are coercion that means the process of exerting forces on any material forcefully against the will or need. Therefore, adhesion,attrition and abrasion are the process of tool wear .So the correct option is (d)
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
