Brine is solution-mined from a salt deposit by pumping fresh water into the salt deposit, dissolving salt to make saturated brine, and pressurizing the brine to the surface, where it is stored in a tank for further processing. The well consists of two concentric pipes. Fresh water flows down the annulus, and brine flows up the center pipe. Assumptions: Pump is at 0 ft elevation relative to grade. Level in the brine tank is 20 ft above grade. Bottom of annulus is 1,000 ft below grade. Salt dissolves quickly, so the annulus contains fresh water, and the cavity and the central pipe contain saturated brine. Water density is 62.4 lb/ft³. Brine density is 1.2 times the water density. Friction loss from the pump to the brine tank is 50 ft of water. The required pump discharge pressure (psig) is most nearly: 11 02 O A. O B. 119 108 O C. O D. 97 87
