Answer: Hello the question is incomplete below is the missing part

Question:  determine the temperature, in °R, at the exit

answer:

T2= 569.62°R

Explanation:

T1 = 540°R

V2 = 600 ft/s

V1 = 60 ft/s

h1 = 129.0613  ( value gotten from Ideal gas property-air table )

<em>first step : calculate the value of h2 using the equation below </em>

assuming no work is done ( potential energy is ignored )

h2 = [ h1 + ( V2^2 - V1^2 ) / 2 ] * 1 / 32.2 * 1 / 778

∴ h2 = 136.17 Btu/Ibm

From Table A-17

we will apply interpolation

attached below is the remaining part of the solution

Fatigue failure occurs under the condition of (a) High elastic stress (b) High corrosivity (c) High stress fluctuations (d) High
Harlamova29_29 [7]

Answer:

Fatigue occurs under conditions of high elastic stress, high stress fluctuations and high rate of loading

Explanation:

 According to many definition of fatigue failure the fatigue occurs when in an especifyc point of the object there is involved many forces and tensions.

 That tensions needs to be big in magnitud, de variations of the efforts it has to be with a lot of amplitude and the loading in the object it has to be with a lot of number of cycles.

 If in the all of these three conditions are present the fatigue failure it would appear.

If an athlete can row at a rate of 50 m/min, how many days would it take to cross the Atlantic (≈3000 mi)?
lana [24]

The kinematics we can find the time to cross the Atlantic is 67 days.

The kinematics studies the movement of the body making relationships between the position, the speed and the acceleration of the same.

The average velocity is defined as the relation between the displacement between the time of the interval

           v = \frac{\Delta x}{t}

           Δt = \frac{\Delta x}{v}

 

Where v is the velocity, x the displacement t time

In this case they indicate the displacement is Δx = 3000 mi and the speed is v = 50 m / min

The system of units allow data to be exchanged with precision and safety, for this there is currently the international system of measurements (SI), where the unit of length is the meter and the unit of time is the second, let's reduce the magnitudes given to these units.

           Δx = 3000 mi (  ) = 4.828 10⁶ m

            v = 50 m / min ( ) = 0.833 m / s

Now we can calculate the time to cross the Atlantic

            Δt = 4.828 10⁶ / 0.833

            Δt = 5.796 10⁶ s

Let's reduce to days

            Δt = 5.796 10⁶ s (  ) (  )

            Δt = 67 days

In conclusion using kinematics we can find the result of the time to cross the Atlantic is 67 days.
