What are the importance of crystallography in geology

1 answer:

8 0

Answer:Crystallography is useful in phase identification. When performing any process on a material, it may be desired to find out what compounds and what phases are present in the material. Each phase has a characteristic arrangement of atoms.

Consider a hot working operation in which there is no work hardening, but the flow stress is sensitive to the strain rate. Calcu

alexandr402 [8]

Explanation:

You can use Hollomon's equation to estimate this.

Y_f is the flow stress.

K is the strenght coefficient or constant.

e is the strain

n is the strain hardening exponent.

You should be able to solve for e given the data in the problem statement.

Water is the working fluid in a Rankine cycle with reheat. The turbine and the pump have isentropic efficencies of 80%. Superhea

zheka24 [161]

Answer:

A) 3783.952 kJ/kg

B) 34.5%

C) 2476.67 kJ/kg

Explanation:

A) Determine the rate of heat addition entering the first-stage turbine

Qin ( 1st stage ) = ( h1 - h6 ) + ( h3 - h2 )

= ( 3321.4 - 164.07 ) + ( 3438.566 - 2811.944 )

= 3783.952 kJ/kg

h values are gotten from super heated table 

B) Determine the thermal efficiency

n = 34.5%

attached below

C) Rate of heat transfer from working fluid passing through the condenser to the cooling water

Qout = h4 - h5

= 2628.2 - 151.53

= 2476.67 kJ/kg

1. Two aluminium strips and a steel strip are to be bonded together to form a composite bar. The modulus of elasticity of steel

yarga [219]

Answer:

1.933 KN-M

Explanation:

Determine the largest permissible bending moment when the composite bar is bent horizontally

Given data :

modulus of elasticity of steel = 200 GPa

modulus of elasticity of aluminum = 75 GPa

Allowable stress for steel = 220 MPa

Allowable stress for Aluminum = 100 MPa

a = 10 mm

First step

determine moment of resistance when steel reaches its max permissible stress

next : determine moment of resistance when Aluminum reaches its max permissible stress

Finally Largest permissible bending moment of the composite Bar = 1.933 KN-M

attached below is a detailed solution

11111nata11111 [884]

A distillation column is an essential item used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities. Fractionating columns are used in small scale laboratory distillations as well as large scale industrial distillations.
