What is the maximum height the higher reservoir can sit and be filled using a fixed-speed pump with 1-1/4 HP of input and a 57% efficiency rating at 30 GPM of flow? The suction line is 30ft of 1-1/4” schedule 40 steel pipe. The discharge line is 1” schedule 40 steel pipe and is horizontal for 10 ft.

Problem 5- Two reservoirs are connected by 198ft of 2-in diameter tubing. What is the flow rate when the difference in elevation is 50ft? (v= .001 ft²/s)

This is a practice problem for an upcoming test, but I'm not really sure which direction to solve it in. If I use a basic pressure equation do I have to do iterations? Cause we should be able to take a ratio of flow in both pipes. Any information on the direction of how to solve this problem will be extremely helpful, as well as solving it.

Absolute Open Flow (AOF) Is the maximum flow rate into the wellbore when the BHP is zero; It’s a theoretical flow rate, which sometimes reflects the ability of the reservoir to deliver fluid into the wellbore Select one: True False
