Thankyou Littleinch. Is there any way for finding the pressure ( gauge pressure ) in the filter theoretically...? Is there any formula for finding it..? Not only for the filter I'm asking generally. Here by positioning a perticular pump, we can predict the result flow through the system...

Hii. Thanks alot for the rplys I did the calculation for the system. Pls take a look on the attachment. Is it the right way..? Also, How can we find the pressure on each area of the system.. For example, I have the filter which have a maximum capacity of 4bar pressure. How can I find the...

Thanks for your rplys.. Now I understood. Is there any issue for connecting pipes larger than the pump connection on the pump by reducing on the pump area. Because here I use 4" pipes. Can I connect a centrifugal pump having 2" connections on this 4" pipe? Is there any issue for that

Thanks for your rply Actually I have an over flow pool, where the overflowing water is falling to the tank through gravity. The tank is located in the pump room. So from the pump room I need to pump the water to the pool which is located 2 floor above ( 7m heigh) for making the pool overflow. I...

I was doing the head loss calculation for my swimming pool system for sizing suitable pump for filtration. Here I can use a maximum of 4" pipe. I calculated thr head requirement for my system. Here I have 7m static head and the friction losses around 13m. But I need to reduce the friction loss...

Hi Is it safe for keeping the pressure inside a high pressure PVC pipe for more than one day to test leakage? Is there any technical issue for that?

I'm trying to use Epanet for calculating headloss. But I'm not getting the idea of the software clearly. I'm using a pump for recirculating water through the filter for cleaning the pool. Its just a simple system having pool, pump and filter. Water comes from 2 seperate lines and entering the...

THANKS FOR YOUR RESPONSES GUYS... I got your points.. Actually I think this is the best thing that happening on the internet, for me.. This kind of active community is very rare I think... I have one doubt balance., If the pump is continuously pushing water why the limit of head is there...

Thanks for your replies guys... Jst consider it in a large view.. Here I want to transport water through a large pvc cylinder of diameter 6m to 22m height. I'm using a 1hp pump that provides a head of 22m at 10GPM. The pump connection is just 2". I'm going reduce the cylinder bottom to 2" so...

Actually for head loss calculation for a selection of a pump, we are taking the frictional loss plus static head. Here, the static head we are considering is vertical height between the suction water level and discharge water level, it is independent of the pipe size we are using. That is; for...

LittleInch , Fel3... Thanks for your valuable responses.... I got your point, that pump curve doesn't depend on the piping system whatever we are doing. we just want to find the head loss occur in our piping system at a required flow rate and find the pump that produce that much energy by...

thread194-343587 I'm working in a swimming pool construction company as a mechanical engineer. Actually I'm not clear about how the head-flow curve mentioned for a pump.. The pump is coming with a standard connection of 2" or 3" likewise. so I think the head loss curve only means for the...
