Answer:
MRR = 1.984
Explanation:
Given that
Depth of cut ,d=0.105 in
Diameter D= 1 in
Speed V= 105 sfpm
feed f= 0.015 ipr
Now the metal removal rate given as
MRR= 12 f V d
d= depth of cut
V= Speed
f=Feed
MRR= Metal removal rate
By putting the values
MRR= 12 f V d
MRR = 12 x 0.015 x 105 x 0.105
MRR = 1.984
Therefore answer is -
1.944
Defining the radius of area throat to inlet we would have that the proportional relationship would be
This equation or relationship is obtained from continuity where
Now applying the Bernoulli equation between inlet and throat section we have,
Here,
Then for a Venturi duct, the velocity of the airplane will be
Our values are,
Replacing,
Therefore the velocity of the airplane is 154.7ft/s
Answer:
E = 207 GPa
Explanation:
Young's modulus is given by following equation:
Where and are stress and strain, respectively.
By replacing terms:
Answer:
Angle of discharge make at the edge of tube=64.9 degrees.
Answer:
It is a perpetual motion machine.
Explanation:
The claim of an inventor is not valid because a device can not deliver more energy than it input or there is no device that can produce more energy than it input. Therefore, the compressor cannot produce more energy as compared to another conventional heating system that runs by the e power input. However, the claim of inventor violates the rule or first law of thermodynamics and So, it is only a perpetual motion of first kind PMM1.
