Answer:

Pink block = 1.4 cm

Green block= 1.5 cm

Blue block= 1.7 cm

Explanation:

Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.

Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)

Knowing this, the measures of each block are.

Pink block = 1.4 cm

Green block= 1.5 cm

Blue block= 1.7 cm

Feel free to ask for more if needed or if you did not understand something.

Answer:

Poissons ratio = -0.3367

Explanation:

Poissons ratio = Lateral Strain / Longitudinal Strain

In this case, the longitudinal strain will be:

Strain (longitudinal) = Change in length / total length

Strain (longitudinal) = (8.40392 - 8.4) / 8.4

Strain (longitudinal) = 4.666 * 10^(-4)

While the lateral strain will be:

Strain (Lateral) = Change in length / total length

Strain (Lateral) = (2.09967 - 2.1) / 2.1

Strain (Lateral) = -1.571 * 10^(-4)

Solving the poisson equation at the top we get:

Poissons ratio = -1.571 / 4.666                                     <u>( 10^(-4) cancels out )</u>

Poissons ratio = -0.3367

What is the thermal efficiency of this reheat cycle in terms of enthalpies?
schepotkina [342]

Answer:

   \eta =\dfrac{\left (h_3-h_4\right )+(h_5-h_6)-(h_2-h_1)}{(h_3-h_2)+(h_5-h_4)}

Explanation:

For close gas turbine:

       Gas turbine works on Brayton cycle.Gas turbine have lots of applications like ,it is use in aircraft,in land applications etc.

Reheating is the method to improve the efficiency of the gas turbine.In reheating gas is expanding in two turbine instead of one turbine alone.Two turbine like high pressure turbine and low pressure turbine are used for expansion.

In the above diagram 1-2 is a compressor,2-3 heat addition,3-4 high pressure turbine,4-5 reheating of cycle 5-6 low pressure turbine,6-1 heat rejection,

We know that    \eta =\frac{W_{net}}{Q_{s}}

Now take h_{1},h_{2},,h_{3},h_{4},h_{5},h_{6} represent the enthalpy of point 1,2,3,4,5,6 in the cycle respectively.

So total heat supplied Q_S=

\left (h_3-h_2\right )+\left (h_5-h_4\right )

Net work out put

W_{net}=\left (h_5-h_6\right )-\left (h_2-h_1\right )

So efficiency   \eta =\frac{W_{net}}{Q_{s}}

      \eta =\dfrac{\left (h_3-h_4\right )+(h_5-h_6)-(h_2-h_1)}{(h_3-h_2)+(h_5-h_4)}
