Which of the following is the equation of a spherical ball of radius r, settling under gravity through a fluid, if acceleration due to gravity is considered as 10 m/s2?

Question

TuteeHUB · Accepted Answer

u = 4x  (  sqrt {  frac {r   times ( P    )}{Cd   times  }}  )

TuteeHUB · Answer

u = 4x  (  sqrt {  frac {5   times r   times ( P    )}{3   times Cd   times  }}  )

TuteeHUB · Answer

u = 4x  (  sqrt {  frac {r   times ( P    )}{Cd   times  }}  )

TuteeHUB · Answer

u = 5x  (  sqrt {  frac {5   times ( P    )}{3   times Cd   times  }}  )

TuteeHUB · Answer

u =   (  sqrt {  frac {8   times ( P    )}{3   times Cd   times  }}  )

1.	Which of the following is the equation of a spherical ball of radius r, settling under gravity through a fluid, if acceleration due to gravity is considered as 10 m/s²?
A.	u = 4x ( sqrt { frac {5 times r times ( P )}{3 times Cd times }} )
B.	u = 4x ( sqrt { frac {r times ( P )}{Cd times }} )
C.	u = 5x ( sqrt { frac {5 times ( P )}{3 times Cd times }} )
D.	u = ( sqrt { frac {8 times ( P )}{3 times Cd times }} )
Answer» B. u = 4x ( sqrt { frac {r times ( P )}{Cd times }} )
