A cylindrical tank contains three liquids of specific gravities: 0.80, 1.00, and 1.50. Each liquid has a thickness of 0.60m and the tank is 1.20m in diameter. If a circular orifice 100mm in diameter is placed at the bottom of the tank to drain the fluid contents with the coefficient of discharge C = 0.650, then: Determine the time to remove the second liquid.

Question Certain fluid parameters are provided The inner cylinder, with a diameter of 20 cm, remains stationary, while the outer cylinder, with a diameter of 21 cm, holds the liquid up to a height of 30 cm. There is a 1.0 cm gap between the bottom of the two cylinders. By rotating the outer cylinder at a speed of 200 revolutions per minute (r.p.m.), the torsion meter attached to the inner cylinder registers a torque of 6.0 N-m. a. Determine the toque on the bottom in terms of b. Determine the toque on the surface in terms of ..... c. Determine method the viscosity of a liquid (N-sec/m^2)(Ans up to 2 decimal) μ (Ans up to 4 decimal) ..u.(Ans up to 4 decimal) using the rotating cylinder
