A cylindrical container with a massless and frictionless piston is filled with water up to a height h, as shown in the schematic. What mass m should be placed on the piston so that the water flow rate through the opened valve doubles? Consider that piston area A₁ = 0.05 m2, valve area A2 = A₁/8, h = 0.9 m, Pwater = 1000 kg/m³, and g = 9.80 m/s².
