A question in GATE 2012 Metallurgical Engineering Paper with Solution has been updated:

Common Data for Questions 48 and 49:

A steel ball (density  \rho_{steel} = 7200  kg/m^3) is placed in an upward moving liquid Al (density  \rho_{A1} = 2360\ kg/m^3 , viscosity  \mu_{A1} = 1\ x\ 10^{-3} Pa.s and Reynolds number =  5\ x\ 10^5) . The force (F) exerted on the steel ball is expressed as

 F = f\ \pi\ R^2\ (\rho_{A1}V^2/2)

where, f is friction factor (=0.2), v is the velocity of liquid Al and R is the radius of steel ball.

The force exerted on the steel ball is

  1. 0.52 N
  2. 1.67 N
  3. 8.32 N
  4. 6.70 N
