<br />Since both restrictions apply to a 113-day pumping period that <br /> <br />ends at the end of the season, intuitive reasoning suggests that the <br /> <br />restriction on volume pumped will dictate the pumping rate during <br /> <br />., <br /> <br />shorter periods at the end of the season, and that the restriction <br /> <br />on volume of stream depletion will dictate both rate and time of <br /> <br />pumping for periods in the first part of the season. <br /> <br />Part (2) <br /> <br />Begin pumping 60 days after the beginning of the season. Test <br /> <br />reasoning that the restriction on volume pumped applies. <br /> <br />Qt = 150 acre-ft, <br /> <br />t = 90 days, <br /> <br />_tT/_a2_S = 90 days <br />209 days <br /> <br />= 0.43. <br /> <br />From Curve B: <br />- <br /> <br />1080 <br /> <br />::!./Qt = 0.13 <br /> <br />v = 0.13 (150 acre-ft) = 19.5 acre-f~ <br /> <br />therefore,the restriction on volume pumped does apply, <br /> <br />150 acre-ft <br />pumping rate = = 1.67 acre-ft/day. <br />90 days <br /> <br />25 <br />
