Two Tanks

Level

Tanks A and B are identical, and both pumps are also identical except for the positions of connection to the tanks.
If we run the water pumps at the same time, which tank will become full first?
Both will become full at the same time
Tank B
Tank A

All pumps have a characteristic or performance curve that describes the flow rate produced at net or total head. sample chart as below.
if we look at the tank B we will find that the pump will be require to work on the Max head all the time, and that's mean it will work with a lower rate.
but for the tank A, the pump will start working on the Min head (high rate) and the rate will gradually decreases as the water level increasing in the tank.
therefore tank A will be full first.
