For a Cu-Ni alloy containing 53 wt.% Ni and 47 wt.% Cu at 1300°C, calculate the wt.% of the alloy that is solid and wt.% of alloy that is liquid.

The question is incomplete. The complete question is --

An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 1.01 cm and the young's modulus of aluminum is 69 GPa, determine the following :

1. the interference value, i

2. the radial pressure at the interference of the collar and the rod

3. the maximum effective stress in the collar

4. if the yield strength of aluminium is 200 MPa and assume a safety factor of 1.5, will the aluminium collar break

Solution:

Given :

Inner radius of the collar = 1 cm

So, inner diameter, [tex]$d_1$[/tex] = 2 cm

Outer radius of the collar = 12 cm

So, outer diameter, [tex]$d_2$[/tex] = 4 cm

The aluminium rod diameter, d = 1.01 cm

Now, from the figure, we can see that there will be no interference and so the rod will easily insert inside the collar.

1. So, the interference , i =0

2. The radial pressure is also 0.

3. There will be no stress developed. So the maximum effective stress is 0

4. The collar will not break

Answer:

S = 0.10253 kW/k

Explanation:

Given data:

Velocity of oxygen ( V ) = 70 m/s  

Diameter of pipe = 12-cm = 0.12 m

At entrance

pressure of oxygen ( p1 ) = 240 kPa

Temperature of oxygen ( T1 ) = 20°c  = 293 k

At exit

pressure of oxygen ( p2 ) = 200 kPa

temperature of oxygen ( T2 ) = 18°c = 291 k

First calculate specific volume of oxygen at inlet

V1 = [tex]\frac{RT1}{P1}[/tex]  -------- ( 1 )

  R = 0.2598 KJ/kgk ( property of oxygen )

  T1 = 293 k

  P1 = 240 kpa

substitute values into equation 1

V1 = 0.3172 m^3/kg

next we calculate the mass flow rate of Oxygen

m = [tex]\frac{A1V}{v1}[/tex] ----- ( 2 )

A1 ( area of pipe ) = 0.0113 m^2 ( calculated )

V = 70 m/s

V1 = 0.3172 m^3/kg

substitute value into equation 2

m ( mass flow rate of oxygen ) = 2.4936 kg/s

Finally calculate the rate at which entropy is generated in the pipe

S = [tex]m( C_{p} In\frac{T2}{T1} - RIn\frac{P2}{P1} )[/tex]   --------- ( 3 )

[tex]C_{p}[/tex] = 0.918 kj/kgk  ( property of oxygen )

T2 = 291 k

T1 = 293 k

P2 = 200 kPa

P1 = 240 kPa

substitute values into equation 3 above

S = 0.10253 kW/k

Answer:

True :)

Explanation:

If this is a true or false question.

The discoloration is when the color of a particular thing comes off or changes, fading from its original color. In other words, when the original color of anything changes or wanes off, then that is called discoloration. The statement is true.

This chemical shift occurs for a number of reasons, including its interaction with other elements nearby or the unfavorable effects of other elements it comes into touch with.

Water leaks may create cases of discoloration on walls, surfaces, even ceilings, and pipes. As a result, the surface progressively changes and becomes moist.

Discoloration puts the surrounding region in danger in addition to altering the part(s) or area's look and durability.

Since a change in that region or component is required, the raw material(s) used are wasted. The claim that discoloration results in the waste of raw materials are thus accurate.

Solution :

Given

[tex]$t_1=2+x_1$[/tex]

[tex]$t_2=1+x_2$[/tex]

Now,

[tex]$P(h<5)=1-P(h \geq5)$[/tex]

[tex]$0.4=1-P(h \geq5)$[/tex]

[tex]$0.6=P(h \geq5)$[/tex]

[tex]$0.6= e^{\frac{-x_1 5}{3600}}$[/tex]

Therefore,   [tex]$x_1=368 \ veh/h$[/tex]

                        [tex]$=\frac{368}{1000} = 0.368$[/tex]

Given,   [tex]$t_1=2+x_1$[/tex]

                 = 2 + 0.368

                 = 2.368 min

At user equilibrium, [tex]$t_2=t_1$[/tex]

∴  [tex]$t_2$[/tex] = 2.368 min

[tex]$t_2=1+x_2$[/tex]

[tex]$2.368=1+x_2$[/tex]

[tex]$x_2 = 1.368$[/tex]

[tex]$x_2 = 1.368 \times 1000$[/tex]

    = 1368 veh/h

Answer:

0.0432 m^3/s

Explanation:

Internal diameter of smaller pipes = 2.5 cm = 0.025 m

pipa wall thickness = 3 mm = 0.003 m

internal diameter of larger pipes = 8 cm = 0.8 m

velocity of region between smaller and larger pipe = 10 m/s

Calculate discharge in m^3/s

First we calculate the area of the smaller pipe

A = [tex]\pi Dt[/tex] = [tex]\pi ( 0.025 ) ( 0.003 )[/tex]  = 0.00023571 m^2

next we calculate area of fluid between the smaller pipes and larger pipe

A = [tex][\frac{\pi }{4} D^{2} _{L} ] - 3(A_{s})[/tex]

   = [tex][ \frac{\pi }{4} (0.08 )^2 - 3 ( 0.00023571 )][/tex]

   = [ 0.00502857 - 0.00070713 ]

   = 0.00432144 m^2

hence the discharge in m^3/s

Q = AV

   = 0.00432144 * 10

   = 0.0432 m^3/s

Answer:

Earthquake's put vibration and seismic load on a building while wind puts a continuous force throughout the whole structure.

Explanation:

The most important difference between the design of a building that's resistent to earthquakes and resistant to high speed winds is that earthquake's put vibration and seismic load on a building while wind puts a continuous force throughout the whole structure.

Earthquake resistent building are equipped with a base that is isolated from the buildings with several layers of different material which absorb the vibration of the seismic waves and prevent them from reaching to the building.

Wind resistent buildings must have strong foundations and a sturdy structure/material that can withstand high pressure that the wind applies during events such as hurricanes.

Solution :

Given

The number of line that can be written by printer per page = 50 lines

The number of characters that can be written by printer per page = 80 characters.

Number of pages that can be written per minute = 6 pages

The speed for writing characters to the printer can be found by

= 50 x 80 x 6

= 400 characters per sec

In one second the printer has the writing speed of 400 character.

Now each of the character uses = 50 µsec of the CPU time for interrupt.

So in each second, the interrupt overhead = 20 msec

Now using the interrupt driven input/output,  980 msec time can be available for other work.

Thus, the interrupt overhead charges only 2 percent of the CPU, that will hardly affect the program to run.

Solution :

Given

Volume, [tex]$V_1 = 1 \ m^3$[/tex]

Temperature, [tex]$T_1=20 \ ^\circ C[/tex]

[tex]$x_1=0.5$[/tex]

From the saturated water table, corresponding to [tex]$T_1=20 \ ^\circ C[/tex], we get the saturated liquid, vapor specific and the entropy.

[tex]$v_f=1.0010 \ m^3/kg$[/tex]

[tex]$v_g=57.791 \ m^3/kg$[/tex]

[tex]$s_f=0.2966 \ kJ/kg-K$[/tex]

[tex]$s_g=8.6672 \ kJ/kg-K$[/tex]

Now calculating the initial specific volume

[tex]$v_1=v_f+x_1 \cdot(v_g-v_f)$[/tex]

    [tex]$=1.0018+05 \cdot(57.791-1.0018)$[/tex]

    [tex]$= 29.8973 \ m^3/kg$[/tex]

Calculating the initial specific entropy:

[tex]$s_1=s_f+x+1 \cdot (s_g-s_f)$[/tex]

    [tex]$=0.2966+0.5 \cdot (8.6673 - 0.2966)$[/tex]

    [tex]$= 4.48 \ kJ/kg-K$[/tex]

So final volume of the vessel is two times bigger as the initial volume

[tex]$V_2=2 .V_1$[/tex]

    [tex]$= 2 \times 29.8973 = 59.8 \ m^3/kg$[/tex]

If we interpolate the values from tables between [tex]$v_g=57.791 \ m^3/kg$[/tex] and [tex]$v_g=61.293 \ m^3/kg$[/tex], we can get final temperature and specific entropy corresponding to value of [tex]$v_2$[/tex] :

Final temperature, [tex]$T_2= 19.6 ^\circ C$[/tex]

and [tex]$s_2 = 8.68 \ kJ/kg-K$[/tex]

Calculating change in entropy

[tex]$\Delta s = s_2-s_1$[/tex]

     [tex]$=8.68-4.48 = 4.2 \ kJ/kg-K$[/tex]

Explanation:

Answer:

  il(t) = e^(-100t)

Explanation:

The current from the source when the switch is closed is the current through an equivalent load of 15 + 50║50 = 15+25 = 40 ohms. That is, it is 80/40 = 2 amperes. That current is split evenly between the two parallel 50-ohm resistors, so the initial inductor current is 2/2 = 1 ampere.

The time constant is L/R = 0.20/20 = 0.01 seconds. Then the decaying current is described by ...

  il(t) = e^(-t/.01)

  il(t) = e^(-100t) . . . amperes

Answer:

115 Ib/ft^3

Explanation:

To determine the maximum dry density in Ib/ft3 we have to calculate :

Bulk unit weight ( yb ) ; W / v

Dry unit weight ( yd. ) :  yb / ( 1 + w )

For every set of data given

assuming  v = 1/30 ft^3

calculating for the 3 data set ( maximum dry density )

weight of soil (W) = 4.40

moisture content (%) (w) = 15.0 = 0.15

Bulk unit weight (yb) = 4.40 / (1/30)  = 132 Ib/ft^3

Dry unit weight ( yd. ) = 132 / ( 1 + 0.15 ) = 114.702 Ib/ft^3

therefore after calculations the maximum dry density in Ib/ft^3 ≈ 115 Ib/ft^3
