Inflow Time Discharge Outflow Discharge Mean Storage Accumulative (cum/s) (cum/s) Storage 0 20 20 0.00 12 191 30 40.25 40.25 24 249 120 72.50 112.75 36 176 29.25 142.00 48 110 -16.50 125.50 60 82 135 -26.75 98.75 72 62 116 -26.75 72.00 -24.00 48.00 68 - 19.50 28.50 108 28 52 -15.00 13.50 1. Identify the time interval per each reading. 2. Identify the difference in flow from inflow peak discharge to outflow peak discharge. 3. Tabulate the modified inflow and outflow discharge assuming the value of the reduction factor "x" is (2-decimal places): 164 84 48 90 96 32 X = 0.250 4. Compute the storage constant (day/s) using least square method, assuming the value of the reduction factor "x" is (5-decimal places): Note: Refer to your set designation 5. Compute the a (day/s) using least square method, assuming the value of the reduction factor "X" is (5-decimal places): Note: Refer to your set designation 6. Using your regression line function based on the storage constant and a, calculate the value the response value with an input value = 20. Note: Refer to your set designation 7. Calculate the correlation coefficient (5-decimal places). Note: Refer to your set designation
