In a paint manufacturing process, two different colored paints are being mixed in an infinitelylarge drum.Paint A, with a concentration of 30% pigment, is pumped into the drum at a rate of 10 liters perminute.Paint B, with a concentration of 17% pigment, is pumped into the drum at a rate of 17 liters perminute.Both paints have the same density of 1.0 kg/liter.If the mixture is cotinuously stirred and drained from the drum at a rate of 22 liters perminute, what isthe concentration of pigment in the resulting mixture?

An 80m deep and 100m wide river flows from the left to the right off the page. An action will release two sources of oil to the river: (1) the indirect runoff of oil accumulated on a bridge that runs off site and crosses over the river and (2) the direct and permitted discharge of water containing oil from the activities onsite (a water pollution control plant) to the river. The oil has a molecular weight of 100 g/mol, it fully dissolves in the river water, and it decays in the river with a rate constant of 0.2 d-1. Estimate the potential impact of this action on the concentration of oil in the river at a location 500m downstream of the WPCP. (1) bridge runoff Q1 = 1 m's C = 1 mol/m (2) WPCP discharge Q2 = 50 m's C2 = 0.01 mol/m Qin = 1000 m³'s Cin = 0.001 mol/m? --500m- 500m- -500m 80m 100m a. Recommend the x, y, and z dimensions of the CV. Justify your recommendations. b. Estimate the oil concentration in the water 500m downstream of the WPCP assuming steady and 1D mixed. c. Sketch…
