Compute the constant outflow from a 500 hectare reservoir for a 30 day period during which the reservoir level dropped half a meter despite an average upstream inflow of 200,000 m^3/day. during the period, the total seepage loss was 3 cm, total precipitation was 10 cm, and the total evaporation was 8.5 cm. (1 hectare = 10^4 m^2.)
