A vertical cylinder (Fig. P3.227) has a 61.18-kg piston locked with a pin, trapping 10 L of R-410a at 10◦C with 90% quality insi

de. Atmospheric pressure is 100 kPa, and the cylinder cross-sectional area is 0.006 m2. The pin is removed, allowing the piston to move and come to rest with a final temperature of 10◦C for the R-410a. Find the final pressure, the work done, and the heat transfer for the R-410a.

The concentration of carbon monoxide (co) in an exhaust gas is 1x10^4 ppmv. what is the concentration in mg/m^3 at 25 and 1 atm
Mrrafil [7]

Answer:

1.1451 x 104 (11451.13)mg/m3

Explanation:

1 ppmv is defined as one volume of a contaminant or solid(CO)(mL) in 1 x 106 volume of solvent/water.

1ppmv = 1mL/m3

Concentration in mg/m3 = volume in ppm x molecular weight x pressure(kPa)/( gas constant x temperature(K)

Molecular weight of CO = 12 + 16

= 28g/mol

Temperature = 273.15 + 25

= 298.15K

Pressure = 1 x 101.325kPa

= 101.325kPa

Ppmv = 1 x 10-4ppmv

Gas constant, R = 8.3144 L.kPa/mol.K

Concentration in mg/m3 = (1 x 104 * 28 * 101.325)/(8.3144 * 298)

= 1.1451 x 104mg/m3

= 11451.13 mg/m3

Lets assume, a represents the edge length (lattice constant) of a BCC unit cell and R represents the radius of the atom in the u
uranmaximum [27]

Answer:

4\ R=\sqrt 3\ a

Explanation:

Given that

Lattice constant = a

Radius of unit cell cell =R

Atom is in BCC structure.

In BCC unit cell (Body centered cube)

1.Eight atoms at eight corner of cube which have 1/8 part in each cube.

2.One complete atom at the body center of the cube

So the total number of atoms in the BCC

 Z= 1/8 x 8 + 1 x 1

Z=2

In triangle ABD

AB^2=AD^2+BD^2

AB^2=a^2+a^2

AB=\sqrt 2\ a

In triangle ABC

AC^2=AB^2+BC^2

AC=4R

BC=a

AB=\sqrt 2\ a

So

16R^2=2a^2+a^2

4\ R=\sqrt 3\ a

So the relationship between lattice constant and radius of unit cell

4\ R=\sqrt 3\ a

What is the relationship between mechanical stress inside of a cylindrical part with a given force applied to it
Oliga [24]

The relationship between mechanical stress inside of a cylindrical part with a given force applied to it is stress = force/area.

<h3>How is pressure associated with strain?</h3>

The utility of pressure offers upward thrust to strain, however now no longer the opposite manner around. A pressure is a push or pull upon an item attributable to the item's interplay with some other item while Stress is an inner resistance to supplied through the frame itself each time it's far beneath a few type of deformation.

Stress is denoted through σ. It is represented as N/m2. Stress formulation is made use of to locate carried out on any given frame if pressure and region on which pressure is exerted is given withinside the problem.
