A. The factor by which a machine multiplies a force
        
             
        
        
        
Answer:
The circulation around the cylinder is 0.163 
Explanation:
Given : 
Velocity of spinning cylinder  
 
Sea level density  
 
Sea level span  
 
Lift per unit circulation is given by,
   
Where  circulation around cylinder
 circulation around cylinder
    
    
     
 
Therefore, the circulation around the cylinder is 0.163

Answer:
a) 84.034°C
b) 92.56°C
c) ≈ 88 watts
Explanation:
Thickness of aluminum alloy fin = 12 mm
width = 10 mm
length = 50 mm
Ambient air temperature = 22°C
Temperature of aluminum alloy is maintained at 120°C
<u>a) Determine temperature at end of fin</u>
m = √ hp/Ka
    = √( 140*2 ) / ( 12 * 10^-3 * 55 )
    = √ 280 / 0.66 = 20.60
