Consider a rectangular plate of width B = 1m (measured in the direction normal to the plane of this sheet) and negligible thickness, which separates two fluids of densities ρ and ρw. A mass of density ρs is supported by an inextensible rope that passes through a pulley connected to one end of the plate. Consider that ρ = 1.59ρw and ρs = 2.40ρw, where ρw = 1000 kg/m3. Determine the volume that this mass must have for the system to remain in equilibrium, as shown in the figure.

A storage tank of a treatment water has a holding capacity of 750 m' up to an overflow point. The treatment water having silica content of 0.003 mg /L is flowing in to a tank at a rate of 30 L/sec. the out flow from the tank to the high pressure boilers is 30 L/sec. With time the quality of treatment water increased to 0.025 mg/L. Assuming that the inflow in to and out flow from the tank remains constant at 30 L/sec, calculate the time required for the silica content in the storage tank to increase to 0.01 mg/L.
