Discuss the below:
Q: The three-legged manometer in Fig is filled with water to a depth of 20 cm. All tubes are long and have equal small diameters. If the system spins at angular velocity O about the central tube,
(a) Derive a formula to find the change of height in the tubes;
(b) Find the height in cm in each tube if O = 120 rev/min [HINT: The central tube must supply water to both the outer legs.]
