The rectangular cistern (storage tank for rainwater) shown has its top 5 ft below ground level. The cistern, currently full, is to be emptied for inspection by pumping its contents to ground level. Assume that the water weighs 62.3 lb/ft³. Complete parts a. through d. below. How much work does it take to empty the tank? 20 (Round to the nearest integer as needed.) 10 ft Ground level a. How much work will it take the empty the cistern? Set up an integral to find the work done. W= 1 b. How long will it take a 2-hp pump, rated at 325 ft-lb/sec to pump the tank dry? 15 ft 21 ft minutes (Round to the nearest integer as needed.) c. How long will it take the pump in part b. to empty the tank halfway? (It will be less than half the time required to empty the tank completely.) minutes (Round to the nearest integer as needed.) d. What are the answers to parts a. through c. in a location where water weighs 62.06 lb/ft³? Recall the pump is rated at 325 ft-lb/sec. In a location where water weighs 62.06 lb/ft³, it would take of work to empty the tank. The pump can pump the tank dry in the pump minutes to empty the tank halfway. (Round to the nearest integer as needed.) What are the answers to parts a. through c. in a location where water weighs 62.46 lb/ft³? lb/ft³? Recall the pump is rated at 325 ft-lb/sec. In a location where water weighs 62.46 lb/ft³, it would take the pump minutes. It will take of work to empty the tank. The pump can pump the tank dry in minutes.
