Answer:
The length of the stop tube is based on all the following factors except the diameter of the pipe.
Explanation:
The length of the stop tube is typically determined by factors such as the depth of the well, the desired position of the pump within the well, and the specific requirements of the pumping system. The diameter of the pipe is not directly related to the length of the stop tube, as the stop tube is typically inserted into the well casing or borehole and does not extend through the entire diameter of the pipe. Therefore, the diameter of the pipe is not a factor in determining the length of the stop tube.
