Discharge concerning Recession Constant Solution

STEP 0: Pre-Calculation Summary
Formula Used
Discharge at Time t = Discharge at Time t=0*Recession Constant^Time
Qt = Q0*Kr^t
This formula uses 4 Variables
Variables Used
Discharge at Time t - (Measured in Cubic Meter per Second) - Discharge at Time t is the volumetric flow rate of a stream, which volume of water flowing per rate of time at any time t.
Discharge at Time t=0 - (Measured in Cubic Meter per Second) - Discharge at Time t=0 is the rate of flow of a liquid that moves over a designated point over a fixed period.
Recession Constant - Recession Constant is the ratio of discharge after the unit time step of some specific initial discharge to specific initial discharge, provided both discharges are along the same straight segment.
Time - (Measured in Second) - Time is the continued sequence of existence and events that occurs in an irreversible succession from the past to the present and future.
STEP 1: Convert Input(s) to Base Unit
Discharge at Time t=0: 50 Cubic Meter per Second --> 50 Cubic Meter per Second No Conversion Required
Recession Constant: 0.1683 --> No Conversion Required
Time: 2 Second --> 2 Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Qt = Q0*Kr^t --> 50*0.1683^2
Evaluating ... ...
Qt = 1.4162445
STEP 3: Convert Result to Output's Unit
1.4162445 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
1.4162445 1.416245 Cubic Meter per Second <-- Discharge at Time t
(Calculation completed in 00.004 seconds)
