A lake has a surface area of 50,023 m2 and an overall lake depth of 25.7 m. A single river discharges water into the lake at 5.7 m/s. A downpour results in the river water discharge increasing to 25.6 m3/s. Calculate the effective residence time, in hours, of the in-flowing stormwater in the lake. Assume 365 days/y. Express your answer to three figures.
