An aerated grit chamber receives wastewater at a peak flow rate of 41,920 m³/d. If the depth of water in the tank is 2 m, the opening under the baffle is 0.6 m and the velocity across the bottom of the chamber is 0.2 m/s. If the quantity of the grit is 0.1 m³/1,000 m³ of flow and the length of the chamber is 15 m, calculate the air flow rate per unit length (m³/s.m) and the dimensions of the grit hopper knowing that the depth to width ratio of the hopper is 1.5:1.

A storm sewer is mixed into a small stream. The stream before the mixing point has a NaCi concentration of 25 mg/L. If the storm sewer has a Nacl concentration of 1.8 g/L and the storm sewer flowrate is 2.5 L/min, calculate for the concentration of the salt in the stream after the discharge point (mixing point). The stream has a flowrate of 2.6 cu.m/s. Assume a complete mixing of the storm sewer flow and the stream flow. Assume also that the salt is nonreactive and that the system is at steady state.
