scenario 1
Water tank suspended 4.5m above exit point, run by ½” pe pipe.
scenario 2
2 water tanks(1 for hot water) suspended 4.5m above a single exit point(mixer), run by ½” pe pipe
thanks

1 foot of head = 0.433 psi
1.0 psi = 2.31 feet of head
So about 6 psi
Is your stand and tanks already built?
no difference between the 2 scenarios?
reason i asked is there's a flow chart for the mixer which says function guarantee above 0.85-1 bar
but there's water flow below this pressure.
so it the function is not guaranteed at 6psi. but i dont know if it will be a trickle or sufficient for shower
any expert can advise?
thanks
Same pressure if I have read the question right.Originally Posted by wanna
Both examples have the same head of water so will have the same pressure.
Having two supply pipes to the outlet will increase the flow rate but will not increase the pressure
At 6 psi your shower will be slow and will stop if another faucet is opened in the house.
Either builld a taller tower or add an electric pump
Pumps are cheaper than towers
Well if you have no electricity in the building then you will have to get a higher tower.
How does the water get up into the tank or is it rain water ?
planning to use a diesel pump to draw water from a pond about 250m away...downhill.
have read on the internet it's best to install the pump at the source as it's easier to push water uphill than to install the pump at the base of the house and try to pull it uphill
would appreciate your comments on the type and power of the pump that i will need
thanks
BlackGang can answer that one.
He will need to know the total lift needed not just the distance
Irrigation Water Pumps
seems like i need a centrifugal vertical turbine submersible
the vertical drop is about 100m
horizontal about 200m
actual distance about 250m
plan to run the pump about 1hr a day(or once a few days) to fill up 2000l on the rooftop
i have seen electric pump from grunfos?, mitsubishi and hitachi
diesel pump from honda and the popular china brands being used here.
is the info sufficient to calculate total lift?

I have a deep bore well and the lift to my 2000 litre tank is about 100 metres, so that is very similar to your requirements.
I use a 2HP submersible electric pump
OK, how far will the lift be, thats from the lowest pump setting to the lowest water level that you will have, the surface of the water, dont matter how deep it is.Originally Posted by wanna
as Thetyim said, two tanks will not increase your pressure, just may increase the flow rate
a cheaper alternative would be to use 1" pipe from the tanks; you would get the same pressure but a much better flow rate. You can reduce the pipe size when you get nearer the delivery points
4.5m of water pressure would be good; quite often 2m is sufficient for showers etc
I have reported your post
Ideally, cold water could be lifted (by suction) only a little less than 11 meters (33 ft.) by ANY device or means. This is because of the vapor pressure characteristics of water.
The suction lift of a commercial pump, however is usually limited to only around 6-8 meters of cold water even when it has been primed. This is because of dynamic energy losses in the pumps. Some specialty pumps are designed for high lift, but they will not do you any good in your desired applicaton because they will always be less than about 10 meters..
You will need a high speed centrufugal pump(s) installed. One at the spring plus another one part way up the hill , all to develop enough pressure to : (a) push the water up to a 100 meter (310 ft) higher elevation; (b) overdome the fluid flow energy losses in the pipe and fittings (estimate 5%) ; (c) furnish a usable operating pressure (35 psig) at the points of usage.
Your pump system will need to develop over 175 psig. This will not be found easily. Even two pumps in series at 90 psi each will be hard to find, but they are available from pumping specialists. They might need to be two-stage. Be prepared to see a big price tag
seems like you are getting your units mixed up, don't try to send anything to MarsOriginally Posted by wanna
anyone know how to convert old-fashoined psi to bar?
aha....
1 pound per square inch = 0.0689475729 bar
so you have around 0.4 bar, according to Thetyim
easier to say
1bar = 10m head
Suggest you do a cost trade off. Cost of deisel pumps, generators etc initial and maintenance vs the cost of getting electricity to the site. You may find the long term cost to bring the electricity to the site is better value.
My water tower is 7 metres tall
If I turn the pump off then the downstairs shower works fine but the upstairs shower is a trickle
So 4.5 metres won't give me a shower
