In a flow over a flat plate, the Stanton number is 0.005: What is the approximate friction factor for this flow a)- 0.01 b)- 0.02 c)- 0.001 d)- 0.1

Respuesta :

Answer:

(a) .01

Explanation:

  • stanton number is a dimensionless quantity
  • stanton is expressed as [tex]\frac{heat transer}{thermal capacity}[/tex]
  • stanton number is discovered by Thomas edward stanton

there is relation between friction factor and stanton number and friction factor that is stanton number is half of friction factor

stanton number =[tex]\frac{friction factor}{2}[/tex]

.005=[tex]\frac{friction factor}{2}[/tex]

friction factor =2×.005

friction factor=.01
