Hope that helped!
B)
Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate.
Answer:
μ = 0.038 Pa.s
Explanation:
Given that
V= 1.5 m/s
r= 2 mm
L = 18 cm
If we assume that flow inside the tube is laminar ,then the pressure drop ΔP given as
μ = 0.038 Pa.s
The viscosity of the fluid = 0.038 Pa.s
