A 10 ft by 15 ft rectangular cistern (storage tank for rainwater) has its top 30 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 at the location weighs 62.26 a. How much work is done to pump all the water out of the cistern? b. How long will it take a - hp pump, rated at 367 ft-lb/sec, to do the work in part (a)? c. How much work is done to pump all the water out of a spout 2 ft above the top of the cistern d. How long will it take a hp pump, rated at 367 ft-lb/sec, to do the work in part (c)?
