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
Answer:
The density would be 218.5
Answer:<u><em> Radiation</em></u>
Explanation:
Define office in one sentence.
Capitalize D in define.
Sentence is one, so take away S.
Always add periods at the end of your sentences
Answer:

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 
Now take
represent the enthalpy of point 1,2,3,4,5,6 in the cycle respectively.
So total heat supplied
=

Net work out put
=
So efficiency
