Before rotation the water level in the tube as shown After r

Before rotation the water level in the tube as shown After rotation, the water level is section 2 is moved 15 cm upward. Determine the roation rate of the tube omega(rad/s). For water take p = 100 kg/m^3 and g = 9.81 m/s^2

Solution

solution

rotation rate of tube = ( 2 g² / r )^1/2

= ( 2 X 9.81² / 0.18 )^1/2

  = 32.7 rad/sec
