Answer:
   13/80
Explanation:
The product is ...
   (1 3/10)×(1/8) = (13/10)×(1/8) = (13×1)/(10×8) = 13/80

Answer:
a)COP=5.01
b) KW
 KW
c)COP=6.01
d)
Explanation:
Given 
 = -12°C,
= -12°C, =40°C
=40°C
 For refrigeration
   We know that Carnot cycle is an ideal cycle that have all reversible process.
So COP of refrigeration is given as follows
  ,T in Kelvin.
  ,T in Kelvin.

a)COP=5.01
Given that refrigeration effect= 15 KW
We know that  
 RE is the refrigeration effect
So
5.01=
b) KW
 KW
For heat pump
So COP of heat pump is given as follows
  ,T in Kelvin.
  ,T in Kelvin.

c)COP=6.01
In heat pump
Heat rejection at high temperature=heat absorb at  low temperature+work in put

Given that  KW
KW
We know that  

 
d)
 
        
             
        
        
        
Since the applied stress required for failure due to crack propagation is still higher than 550 MPa, the ceramic is expected to fail due to overload and not because of the flaws 
Explanation:
<u>Plane -Strain Fracture toughness is calculated as</u>
 =
= б
б
F=geometry factor of the flaw
б=Stress applied
 =Fracture toughness
=Fracture toughness
a=Flaw size
<u>Given that </u>
Internal Flaw,a=0.001cm
Fracture Toughness  =45MPa
=45MPa
Tensile Strength б=550 MPa
Geometry Factor, =1
=1
<u>Calculation</u>
An internal Flaw i s 0.001 cm
2a=0.001cm
a=0
