1x175 5x35 7x25
Do you mean 2x = 5x35? If that's the case, then: 5x34 = 2 x34 = 2/5 x = (2/5)1/34 x ≈ 0.97341017614686370994
2x+5x=35 2+5(x)=35 7(x)=35 7*(5)=35 35=35
..........175 ............/\ ..........5x35 ............../\ ............5x7 (remove the dots)
It doesn't make any difference how many sides of the pool are negative edge, only the total number of linear feet of negative edge and how level you can make the edge. The longer the edge the more important it is that it be level, because even small amounts of out of level require huge flow rates to compensate for. Approximate GPM required per linear foot for various water depths: 1/8" - 5 gpm ¼" - 10 gpm ½" - 17 gpm ¾" - 28 gpm 1" - 40 gpm 1.5" - 70 gpm 2" - 105 gpm As a minimum 5x35=175 GPM
