Question

the centrifugal force exerted on rotating turbine blades varies directly as the square of velocity. If the centrifugal force of 1.21 imes10^6:N1.21×106N is acting on the blades that move at 550:mslashsec:550m/sec, find the instantaneous rate of change of the centrifugal force with respect to the velocity as the velocity increases to 8 extbf{[a]}0:mslashsec8[a]0m/sec. Round the answer to the nearest whole number. a=2 , b=3, c=6, d=7 , e= 4. can you please to write 1 sentence for each step if that is possible just as an explanation?

Explanation / Answer

Sure buddy and now concentrate.

We know that the C.F =(M*V2)/R where M is the mass of the body V is the velocity of the body and R is the radius of the circular path or distance sometime.

Now buddy if   8 extbf{[a]}0:mslashsec8[a]0m/sec means 80 m/sec hence the velocity have decreased .

Now V initial was 550 m/sec and V final is 80 m/sec.

So to find the C.F final we can use the relationship Cinitial is 1.21*10^6 N

C.F initial/C.F final=V 2initial /V 2final   

Using the above relation we get C.Ffinal =256 N  

Hence change in centrifugal force is =1.21*106  -256 =1209744 N

The answer may vary as the values provided in the question were not properly represented but whatever are the values the correct process is this.
