Final answer:
To calculate the maximum length of the hose from the eductor to the nozzle, the time it takes for the water to travel from the eductor to the nozzle is required.
Step-by-step explanation:
The maximum length of the hose from the eductor to the nozzle can be calculated using the flow rate and the speed of the water. Assuming a flow rate of 125 gpm (gallons per minute), we need to convert it to a SI unit, such as liters per second. 1 gallon is approximately equal to 3.78541 liters, so 125 gpm is equivalent to 470.6 liters per minute. To convert it to liters per second, we divide it by 60, which gives us a flow rate of approximately 7.843 liters per second.
The speed of water emerging from a nozzleless hose is about 1.96 m/s, as mentioned in the provided reference. Next, we can use the formula Length = Speed × Time. To find the maximum length of the hose, we need to determine the time it takes for the water to travel from the eductor to the nozzle. Without that information, we cannot calculate the maximum length of the hose accurately.
Please provide the time it takes for the water to travel from the eductor to the nozzle, and we can further assist you in calculating the maximum length of the hose.
