Hello friends,
I am trying to calculate the required Q for a double jacket 10m3 vessel heated by a small boiler. If I do the Q=mcdt equation it turns out 500 kg,60 degC difference about 30+Kw.
How ever If I calculate the resistance of heating the water,convection to and throught the copper...
Hello friends,
I need to fill EXACT weight in many 1000L plastic tanks (IBC). To do it I need to pump from one IBC into another. I have a pump to do that, but I have to control the filling. SO I was thinking about a movable filling post (submerged into a concrete bucket/cut drum). The...
Hello friends,
Need your advice regarding a balance point:
A 24L bucket (D=0.3m,H=0.34m) is to be filled with concrete. A 2.4m profile (50mm*50*2) is to be placed into the bucket before it solidifies. I intend to place a chemical identification sign at the top (or another height).
The...
It is a pressure booster pump for a sprinkler system. I assume it is as old as the sprinklers, I only have a motor label.
But thanks anyway.

Another question friends,
Water that is supplied is at 210 PSI pressure. There is additional 2'' pump 7.5KW, 15A that provides additional pressure. How can I calculate what addition(PSI) does that pump produce?

Just found the model, hope to find the data from the supplier. It is 20 year old sprinkler system.
Thanks all.

Hello Friends,
I need to calculate sprinkler LPMM (LPM per 1 meter) spraying capacity.
I know that that we have 12rows*13 units/row =156 units for 1200 M2 of storage.
I also know that the pressure in the sprinkler piping system is 11-12 bar. Water is provided from 1000M3 tank by a 6'' pipe...
Hello Friends,
I have a 4m3 vertical tank. At the bottom, 2'' draining valve.
How to calculate the draining flow? It is obviously height dependent, so if it has a 1m3 water in it?
Thanks.

Not Very noisy, but it bents and after some time the connections leak.
If the new tube is too stiff, it's because it has allot of metal so it will make a specific noise (like one frequency meets a different one), I know it from other places that I have this type of tube. I think it is called an...
I attached a pic to better explain myself.
See the top plastic hose.

Hello Friends,
I have a 2'' 100LPM gear pump, I used it to transfer lubricant additives from the drum to a mixing tank.
I connect the pump to a piping system by a flexible plastic tube.
I want to change this tube to a stiffer hose and my concern is that because pump has vibrations this new...
Hello Friends,
Got a question for you:
I have two underground oil water separators. Each has 2 vents.
I was wondering, can I close or cover them up?
It's a safety concern. A workers foot can get trapped, it's 4'' diameter openings.
Thanks.

The components are:
IPA
NP9 some kind of soap
Buthyl glycole
perfume
, 2'' GS pipe from bottom of the storage tank to the pump, about 4 m long.It's a top fill, from the pump to the 1m3 tank.

Hello friends,
I have a question for you:
We produce a windscreen fluid in a 4m3 storage tank. A centrifugal pump(100-600 LPM) pumps the liquid into a 1m3 tank that feeds the filling machine.
When a 1m3 tank is empty, the pump works to fill the tank.
It is then, the foam is produced, lots of...
Hello friends,
I have a gear pump 1.5'' that pumps 40LMP.
I have a same pump 2'' that pumps 100LMP, under same conditions.
Is there a rule of thump to tell that increase from one diameter to another, increases output by?...
