A cold air-standard Diesel cycle has a compression ratio of 18 and a cutoff ratio of 1.5. Determine the maximum temperature of t
Debora [2.8K]

Answer:

\dot Q_{in} = 228.659\,kW, T_{3} = 1573.662\,K\,(1300.512\,^{\textdegree}C)

Explanation:

The ideal efficiency of the Diesel cycle is given by this expression:

\eta_{th} = \left\{1 - \frac{1}{r^{k-1}} \cdot \left[\frac{r_{c}^{k}-1}{k\cdot (r_{c}-1)} \right]\right\}\times 100\%

Where r and r_{c} are the compression and cutoff ratios, respectively.

\eta_{th} = \left\{1-\frac{1}{18^{0.4}}\cdot \left[\frac{1.5^{1.4}-1}{1.4\cdot (1.5-1)} \right] \right\}\times 100\%

\eta_{th} = 65.648\,\%

The heat addition to the cycle is:

\dot Q_{in} = \frac{\dot W}{\eta_{th}}

\dot Q_{in} = \frac{150\,kW}{0.656}

\dot Q_{in} = 228.659\,kW

The temperature at state 2 is:

T_{2} = T_{1} \cdot r^{k-1}

T_{2} = (330.15\,K)\cdot 18^{0.4}

T_{2} = 1049.108\,K\,(775.958\,^{\textdegree}C)

And the temperature at state 3 is:

T_{3} = T_{2}\cdot r_{c}

T_{3} = (1.5)\cdot (1049.108\,K)

T_{3} = 1573.662\,K\,(1300.512\,^{\textdegree}C)

Relation between Poisson's ration, young's modulus, shear modulus for an isotropic material
poizon [28]

Answer:

 E=2 G(1+2μ)

Explanation:

Isotropic material :

 Those material have same property in all direction is known as isotropic material.

Homogeneous material :

 Those material have same property through out the volume is known as homogeneous material.

Relationship between Poisson ratio ,young modulus and shear modulus:

   E=2 G(1+2μ)

Relationship between Poisson ratio ,bulk modulus and shear modulus:

E=2 K(1-μ)

Where

E is  young modulus.

G is shear modulus.

μ is Poisson ratio.
