multiply the total force personnel of 4,000 by the daily consumption factor of 8 gallons (4,000 x 8 =). This

results in 32,000 gallons per day. The next step is to determine the shortfall, if any, which is the number of

gallons short of the total necessary per day to sustain the force given the full capacity of the equipment

designated for the mission.

capacity of all the ROWPUs at your command to determine the daily water production rate and then subtract

that result from the total daily requirement. The difference between the numbers will be the shortfall if the

result is lower than the total daily requirement. To determine the total production flow, however, you will first

have to calculate the flow of one ROWPU. To do this, use the water production graph (Figure 1-1) to

determine the production flow of one ROWPU.

Before using the water production flow graph (Figure 1-1), you need to have information on the water

quality, TDS, and water temperature. From the scenario, you are given that the water quality is saline, the

TDS is at 20,000 milligrams per liter, and the water temperature is 35C. By applying this scenario

information to the Water Production Flow Graph (Figure 1-1). You can determine the production flow of one

600-GPH ROWPU.
