The inital rate of infiltration of a watershed is estimated as 2.1 in/hr, the final capacity is 0.2 in/hr, and the time constant k, is 0.4 hr-1. Use Horton's Equation to find: A. The infiltration capacity is at t= 2.1 hr and t =6 hr; and B. The total volume of infiltration over the 6-hr period.

QUESTION 2 Kindly answer correctly. Please show the necessary steps

The town of Viracocha discharges 17,360 m³/day of treated wastewater into the Pachacamac Creek. The treated wastewater has a BOD5 of 12 mg/L and a BOD decay constant, k, of 0.12/day at 10 °C. Pachacamac Creek has a flow rate of 0.43 m³/s and an ultimate BOD, Lo, of 5 mg/L. The DO of the river is 6.5 mg/L and the DO of the wastewater is 1.0 mg/L. Compute the DO and the initial ultimate BOD, Lo, after mixing. Draw the Mass Balance Diagram.
