Fluid mechanics question

A jet of water emerges from the upper tank through a nozzle of \( 100 \mathrm{~mm} \) diameter, and falls into a dish of negligible weight as shown below. The submerged volume of the dish is \( 0.12 \mathrm{~m}^{3} \). (a) What is the buoyant force on the dish? (b) What is the velocity with which the water leaves the upper tank? What is the flowrate? (c) What is the velocity of the vertical jet at level AB? (d) What is the weight of the water in the dish (i.e. below level AB)?
