this is fluid mechanics experimental question please solve and explain properly. 'x' in the question is 50 (x=50)

3.-) A liquid at 25C with a density of 1088.3 kg/m' is stirred at (150+x) rpm by means of a 0.1 m diameter turbine type impeller in a 0.3 m diameter tank equipped with 4 battles. The elevation of the liquid, elevation of the impeller, and baffle width are 0.3m. 0.125m, and 0.03m. respectively During stirring, a dynamometer with a torque arm length of 0.1m was implemented to the system and a force of 0.91N was measured. Determine the viscosity of the liquid
