3. An M-rated self-priming centrifugal pump will be used to dewater an excavation during construction. The required pumping volume is estimated at 250 gal/min. The pump will be located 10 ft above the bottom of the excavation. The suction line will consist of 20 ft of 3-in hose, and the discharge line will consist of 80 ft of 3-in hose. Water will be discharged 30 ft above pump level. What is the total head developed

is explained din the attachment.

Step-by-step explanation:

answer: x

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
