Which of the following methods can help determine if additional handlines can be deployed while pumping?

All the methods listed are effective ways to assess whether additional handlines can be deployed while a pump is in operation, making this the most comprehensive choice.

The Percentage Method involves calculating the total flow based on the percentage of the pump's capacity that is being utilized. It allows operators to determine how much water is available for additional lines, facilitating optimal equipment use without exceeding the pump's limits.

The First Digit Method is another practical approach that estimates the flow based on the first digit of the pump's performance rating. By using this method, operators can quickly gauge the potential capacity available for additional handlines, providing a straightforward way to manage and deploy resources effectively.

The Squaring Lines Method is rooted in hydraulics principles, where the flow rate is examined concerning the size of the hoses and their respective pressures. This method offers insights into how many additional lines can be effectively managed based on the hydraulic calculations involved.

Altogether, these methods provide a comprehensive toolkit for pump operators to make informed decisions about deploying additional lines, ensuring safety and efficiency during operations.
