Unformatted text preview: 6 gate valves, GV, at 2.5 ft/100 ft pressure loss factor 1 horizontal swing check valve (used to only allow flow in one direction),CKV at 2.5 ft/100 1 Y-strainer (used to filter trash out of the water), YS at 2.5 ft/100ft 2 flexible couplings (assume same equiv. ft as a regular coupling), FC at 2.5 ft/100ft 1 air separator with a head loss of 5 ft ( used to separate entrained air from the system),AS 1 storage tank heat exchanger with a head loss of 10 ft 1 solar collector flat plate collector array with a head loss of 10 ft. (includes balancing valves) 1 base mounted pump Select a Bell and Gossett series 1510 base mounted pump for this system. Print out the selection and pump curve to submit with your homework submittal. Just for fun, take the developed length of pipe (420 ft) multiply by 1.2 and add the pressure drops for the AS, storage tank and collector array and see if you get about the same answer.
