Question

A liquid is kept in a cylindrical vessel which is rotated​

Answer 1

according to the bernoulli's theorem:p+12ρv2 = constant we know v = r applying these equation at the side wall and centre of the vessel p centre 12ρvcentre2 = p side 12ρvside2 v center = 0pcentre −p side = 12ρr2ω2hρg =12ρr2ω2h = 12gr2ω2 = 1×0.05×0.05×(2π×2)220 = 0.02 m= 2 cm
