Answer:
F= 5 N
V= 4 m/s
Explanation:
Given that fluid is Newtonian fluid .As we know that for Newtonian fluid the shear stress given as
We also know that
Force = shear stress x area of plate
Now by putting the values
Here velocity of fluid profile is linear.
τ= 2.5 Pa
So force = 2.5 x 2
F= 5 N
Now when fluid is replaced by another fluid but force is constant.The height of plate is also constant.
Lets take velocity of fluid is V in the new condition
So we can say that
Now by putting the value
50 x 0.4 = 5 x V
V= 4 m/s
Answer: False
Explanation: The process in which the thickness of a material is reduced with help of two rolls opposing each other it is called as rolling.It is a type of deformation technique that is done on work piece by using compressive forces exerted by rolls working in the opposite direction of reach other. A draft get created in this process which has the difference of initial and final thickness of work piece. Thus, the statement given is false.
