Hi All,
Seeking some advice, in order to increase/maximize my retention time of the tank(hold up volume),
I am designing the suction of a vertical multistage centrifugal pump(CRN), with an "inverted elbow suction" within the FRP tank.
This principle basically helps to bring down the minimum...
Dear All,
I am looking for a type of sampling pump (about 100 L/hr) that has a high suction lift of about 9m (Already considered all the loses).
As far as i know that some peristaltic pumps can achieve such a high suction lift. Is there any special types/alternatives of pumps capable of...
Hello all,
If lets say my tank is 12m tall, my pump rated 7bar, shut off is at 9.1 bar.
While not considering water column/density, where 1bar = 10m, my discharge pressure instruments can be designed as
min Pressure - 0
Normal Pressure - 7+1.2 = 8.2
Max - 9.1+1.2 = 10.3
Is this correct...
Hello All,
I am quite new to this sizing of air compressors and wondering if anyone could advice me on my understanding. Thank you!
1. Lets say the assumptions for the Duty factor and cycles are correct. Why am i getting a Air receiver volume of 30730L, while my Air used in idle time is...
Hello experienced engineers out there,
I am curious what is the difference between Bowl and pump efficiency. When i am evaluating some quotes, some suppliers do quote,
bowl/pump efficiency : 88%/87.7%
Thanks in advance!
Hello all,
I am unsure of how to size a pump when i have multiple discharge points. I have always done 1 suction 1 discharge which is easy and straight forward with only 2 points to consider.
Now i have 5 points to consider..
To keep it simple,
One suction point from an atmospheric tank
4...
