Answer:
Head loss = 28.03 m
Explanation:
According to Bernoulli's theorem for fluids we have
Applying this between the 2 given points we have
Here is the head loss that occurs
Since the pipe is horizantal we have
Applying contunity equation between the 2 sections we get
Since the cross sectional area of the both the sections is same thus the speed
is also same
Using this information in the above equation of head loss we obtain
Applying values we get
Coupling is a process through which a tractor and other farm equipment are coupled (joined) together through the use of a pickup hitch and a tongue, while using them to work.
Basically, a coupling assembly connects (joins or couples) a towed equipment such as a trailer having a tongue to a tractor that has a pickup hitch.
Some of the precautions which must be taken before, during and after coupling a tractor to a towed equipment:
- You should check your path for any hazard before you begin coupling.
- You should check the normal air pressure for the braking system of the towed equipment.
- You should use a<u> low gear</u> when rolling up the landing gear after coupling the two equipment. This is to ensure that the rate at which the landing gear is moving isn't too fast considering the weight of the trailer.

Answer:
h=27.15 KJ/kg
Explanation:
We know that ,Enthalpy of perfect gas depends only on temperature it did not depends on the volume and pressure.But on the other hand enthalpy of real gas depends on the temperature and pressure.
So specific enthalpy(h) is given as follows
For oxygen
From above
So
h=27.15 KJ/kg
Answer:
No it is not a problem
Explanation:
It is not a problem because the stress intensity factor K would approach infinity as you get close to a crack tip and the intensity factor would approach Zero as you get too far away from the crack tip and this is simply because a crack is a notch with zero tip radius .
and The application of stress intensity factor k in respect to present fatigue crack tip is termed " linear elastic fracture mechanics "
