A 350 LaTeX: m^3m 3 retention pond that holds rainwater from a shopping mall is empty at the beginning of a rainstorm. The flow rate out of the retention pond must be restricted to 320 L/min to prevent downstream flooding. What is the maximum flow rate (in L/min) into the pond from a 6 hour storm that will not flood it?

Answer:

Maximum flow rate is 1290L/min

Explanation:

Mass rate of accumulation = mass rate of input – mass rate of output

350m^3 (1000L/m^3) = (x)(6hours)(60min/hour) - (320L/min)(6hours)(60min/hour)

3.5 × 10^3L + 4.65 × 10^3L = x(360min)

X = 1290L/min.
