Answer:
vacancy formation energy of Ni is 1.400 eV
Explanation:
given data
number of vacancies in Ni = 4.7 x
atomic weight = 58.69 g/mol
density = 8.8 g/cm³
solution
we get here N that is
N =
...........1
N = 
N =
and here no of vacancy will be
Nv =
.................2
put here value

take ln both side
Qv = 1.400 eV
so vacancy formation energy of Ni is 1.400 eV

Explanation:
The model for the turbine is given by the First Law of Thermodynamics:

The turbine power output is:

The volumetric flow is:


The specific volume of steam at inlet is:
State 1 (Superheated Steam)

The mass flow is:



Specific enthalpies at inlet and outlet are, respectively:
State 1 (Superheated Steam)

State 2 (Saturated Vapor)

The turbine power output is:

Explanation:
Answer
63 %
Explanation:
It is given that the reservoirs is at the temperature of 627°C and 27°C
So lower temperature that is
= 60°C=273+60=333 K
And the higher temperature that is
= 627°C =273+627=900 K
We know that the thermal efficiency of thermal reservoir = 1-
=
= 0.63 =63 %
So the efficiency of the reservoir is 63%
