What is the total flow when E2 deploys 200' of 2 ½" hose to a water thief with two 75' 1 ¾" sections?

Explanation:
To determine the total flow when E2 deploys the specified hoses, we need to consider the flow rates for each hose configuration. In this scenario, E2 is using 200 feet of 2 ½" hose that typically has a flow rate of about 250 gallons per minute (GPM) when operating at a standard pressure. Additionally, the water thief allows for the addition of two 75-foot sections of 1 ¾" hose. Each 1 ¾" hose section can deliver approximately 150 GPM at the same operational conditions. The first calculation involves the flow from the 2 ½" hose. As mentioned, it flows at around 250 GPM. When the water thief is utilized and the two 75-foot sections of 1 ¾" hose are deployed, they can each add their flow contribution to the overall total. Therefore, calculating the flow from both sections of 1 ¾" hose gives: - First 75' of 1 ¾" hose: 150 GPM - Second 75' of 1 ¾" hose: 150 GPM When you combine the flow from the 2 ½" hose and both sections of the 1 ¾
