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

Answer:
δu/δx+δu/δy = 6x-6x =0 
9r^2
Explanation:
The flow is obviously two-dimensional, since the stream function depends only on the x and y coordinate. We can find the x and y velocity components by using the following relations:  
u =δψ/δy = 3x^2-3y^2
v =-δψ/δx = -6xy
Now, since:  
δu/δx+δu/δy = 6x-6x =0 
we conclude that this flow satisfies the continuity equation for a 2D incompressible flow. Therefore, the flow is indeed a two-dimensional incompressible one.  
The magnitude of velocity is given by:  
|V| = u^2+v^2
     =(3x^2-3y^2)^2+(-6xy)^2
     =9x^4+18x^2y^2+9y^2
     =(3x^2+3y^2)^2
     =9r^2
where r is the distance from the origin of the coordinates, and we have used that r^2 = x^2 + y^2.  
The streamline ψ = 2 is given by the following equation:  
3x^2y — y^3 = 2, 
which is most easily plotted by solving it for x:  
x =±√2-y^3/y
Plot of the streamline is given in the graph below.  
Explanation for the plot: the two x(y) functions (with minus and plus signs) given in the equation above were plotted as functions of y, after which the graph was rotated to obtain a standard coordinate diagram. The "+" and "-" parts are given in different colors, but keep in mind that these are actually "parts" of the same streamline.  
 
        
             
        
        
        
Answer:
Inlet
Explanation:
Consider a laminar forced flow inside a pipe with constant wall temperature, the heat flux will have a higher value near the INLET of the pipe.
This is because the friction factor is experienced at the highest level when a laminar forced flow is at the tube inlet where the thickness of the boundary layer is zero. Also, the friction factor decreases step by step at a lower rate to the fully augmented value.
