Explanation:
There are two rake angle types :
Positive rake
This is the case that occurs when looking from the inner side the face of the cutting tool slopes away from the cutting edge.
Negative rake
This is the case that occurs when the face of the cutting tool slopes away from the cutting edge at the outer side.
Increasing the positive rake angle means that the cutting tool will get sharper thus making the tool weaker. So, brittle material will form discontinuous chips and ductile material will form continuous chip. The tool life may also be reduced.
Increasing the negative rake angle means that the cutting tool will get blunt thus making the tool stronger. So, brittle material will form continuous chips. Results in higher temperature of the tool. Surface finish might increase.
Answer:
The mass flow rate of jet =69.44 kg/s
Explanation:
Given that
velocity of jet v= 60 m/s
Power P=250 KW
As we know that force offered by water F
Power P= F.v
So now power given as
We know that mass flow rate = ρAv
250 x 1000 = mass flow rate x 3600
mass flow rate = 69.44 kg/s
So the mass flow rate of jet =69.44 kg/s
I would go with C but i am not 100 percent on that
A digital solid is a 3D model consisting of vertices, edges, faces, and partially filled or entirely filled interior. It is a complete and unambiguous representation of the object in a precisely enclosed and filled volume in digital space
