2. A pipe crew is installing new storm drainage pipe, using a new pipe laser which allows them to confirm the slope of the new pipe as it is installed. The upstream end of the pipe is located at STA 108+65.35 with an invert elevation of 115.25' and the downstream end of the pipe is located at STA 105+25.50 with an invert elevation of 109.64'. What slope (expressed as a percentage) should be programmed into the laser, if the crew is installing the pipe up-gradient?
