Answer:
critical stress required is 18.92 MPa
Explanation:
given data
specific surface energy = 1.0 J/m²
modulus of elasticity = 225 GPa
internal crack of length = 0.8 mm
solution
we get here one half length of internal crack that is
2a = 0.8 mm
so a = 0.4 mm = 0.4 × m
so we get here critical stress that is
...............1
put here value we get
=
= 18923493.9151 N/m²
= 18.92 MPa
Answer:
True
Explanation:
Actually this are some of the nitty gritty answers and ways to control or stip stress, lemme explain them you see stress most of the time may come from deep thoughts that are and are pushing you to the wall, and you in your state you as you react to that which is so demanding as it makes you tense,so if at you will incorporate physical activities like running, jogging or push ups the psychological tension in you is broken as you focus so much on the activities rather than the tension, then getting enough rest cools the mind and all your thoughts settle as in your brain starts to adapt to chilling and relaxation and enough sleep will actually make ones head to be at peace because if you lack enough sleep you might have an excruciating migraine when you are stressed up and finally relaxation techniques makes the body accept the situation and then you manouver out of it as you grow strongly.
Hope this will help!
Answer: 5.35m
Explanation:
By using energy equation:
exit velocity head = =2.068m
head loss as a function of exit velocity head is=
head loss as a function of exit velocity head =5.35m
Answer:
The circuit is open and on.
Answer:
Explanation:
The adiabatic throttling process is modelled after the First Law of Thermodynamics:
Properties of water at inlet and outlet are obtained from steam tables:
State 1 - Inlet (Liquid-Vapor Mixture)
State 2 - Outlet (Superheated Vapor)
The change of entropy of the steam is derived of the Second Law of Thermodynamics:
