Comment on Why did the proposed *Red Sea–Dead Sea Water Conveyance* project involve pumping water instead of siphoning it?

  Yes, and the highest point in this route was 230m above sea level, requiring 22.8x the uphill ‘push’ that atmosphere could provide.

  But even if the highest point was below 10m and friction was not an issue, you would need hundreds of kilometers of perfectly airtight ‘vacuumed’ pipes. If air leaks into the pipes somewhere along their length, the flow stops.

  Jip if you try to “pull” water higher than 10m at sea level it starts to boil because the pressure drops that low.
