A contractor is placing soil in 10-in loose lifts, each at about 85 pcf. The moisture content is 8% at the time of placement. The optimum water content for the soil is 10%. The contractor has a water truck with a spray bar on the back. She will use it to drive over the dry soil, with the spray bar running, to increase the water content. How fast should the truck move with the spray running a at some flow rate
