Answer:
V = (v1 + v2) / 2 = (8 + 6.5) / 2 = 7.25 m/s average speed
t = 7.2 / 7.25 = .993 sec time to cross patch
a = (v2 - v1) / t = (6.5 - 8) / .993 = -1.51 m/s^2 or 1.5 m/s^2

Answer:
Viscosity of the fluid is
Explanation:
Given
- Length of the concentric cylinders, L=75 cm
- Gap between two concentric cylinders = 1 mm
- The frequency of inner cylinder = 300 rpm
- Torque acting
- Outer diameter of the inner cylinder=15 cm
The Area is given by
The velocity of the layer is layer is given by
Force acting by one layer of the fluid to other is given by F
Now from the Law of viscosity we have
Hence the viscosity of the fluid is
