Q2: Complete the following
1. As shown in Figure 1, oil of viscosity 0.006 kg/m.s fills the small gap of 0.2 mm thickness. The torque T required to rotate the truncated cone at a constant speed (600 r.p.m) is -
Neglect fluid stress exerted on the circular bottom.
2. An open cylindrical tank, 1.2 m in diameter and 1.8 m deep, is filled with water and rotated about its central axis at 60 r.p.m. So the volume of water spilled is - and the depth of water at the central axis is 40 mm.
