The pressure inside the tower estimates the pump’s pressure – is it sufficient to push the liquid through?
Thread Content
The gauge pressure inside the tower is around 59.5 kPa. Due to recent process modifications, I wonder if this pressure, plus atmospheric pressure, equals the pressure of the pump. 103.12 + 59.5 = 162.62 kPa, which is less than 2 kilograms, right? Also, will a 90-degree bend affect the pressure loss? I remember that the pressure loss per meter is the same as that in a straight path.
Judging from the pressure and height at the end, the information provided by the poster is incomplete.
You also need to add the pressure of the liquid inside the tower. Elbow pressure: 1 meter of head is consumed for 3 elbows.
