Water Test & TDS Posted Sat, 29 Jul 2006 21:41:00 +1000 by Chris

I would like to thank Albert for the following email regarding Water Test.

---------------------------------------------------------------------

Chris,

I want to thank you for writing the software for the LSI, it's very simple to use and it seems to work well. I was just curious as to why you decided to leave TDS out of the LSI calculation, maybe you can let me know your thoughts. I have a chlorine generator and my TDS is at 4500 PPM, 3100 ppm of that is from the salt content. Some say you should subtract the salt content in the water from the total TDS reading, others disagree. Can you shed any light on this subject.

By the way, I found another LSI calculator that I liked, thought I would share that with you... it does include the TDS calculation. You have to download the excel file, but it's pretty cool.

 Hope to hear your comments, keep up the good work!!

Albert

---------------------------------------------------------------------

TDS is not actually necessary to calculate the LSI and is a dubious measure in itself. TDS is a measure of the total dissolved solids or all the salts in the water of your pool.  Depending on how you treat your pool, where you live and how you fill it this composition will be different.  TDS measures the conductivity of the water and uses this to calculate the TDS.  Unfortunately different salts have different conductivities so the meter needs to be calibrated for each solution and the result is only relevant for that one water body.  Hence there is no real standard TDS that can be measured. 

More information on this is available in the Information section of The Pool Clinic.

"Work is a marvellous regulator of moral and physical health. All the sadness, all the bitterness, all the grief - I forget, I overlook them in the joy of working. Suffering only has a hold over the lazy."

Learning more... Posted Mon, 25 Jul 2005 21:07:00 +1000 by Chris
Kopji,

There are a variety of ways you can learn more about physics, or any science, depending on what level of understanding you wish to attain. Most cities have a science education centre wish can provide a basic understanding of most fields. These centres are good places to find people who can provide you with information on various fields and they can probably point you in the right direction. For those wanting to be educated in Physics the universities are usually the best places to look. Searching online you will find plenty of websites containing a variety of information but unless you know the source it is hard to verify some information. If you are interested in gaining further education in Physics I would recommend having a look at the university websites online to see what relevant courses they are offering.

You say life support I say ... Posted Sun, 19 Jun 2005 20:48:00 +1000 by Chris
Talking to a close friend of mine who is an ICU registrar at a major Sydney hospital I was shocked to discover that a large number of patients are not aware of the meaning of life support. When faced with the choice of intubating or ventilating a seriously ill patient most family members are keen to do whatever is necessary to keep the patient alive. Many however do not recognise that a ventilator is a life support machine. Many who go on life support never come off. When asked would you like the patient on life support the same family members often refuse. This is an area where education is necessary so people understand. For the elderly these procedures can be the final steps in keeping them alive and when faced with the need for ventilation it is important to remember that this is life support. In a seriously ill or elderly patient it is important to remember that while these measures can prolong life they cannot increase the quality of life. Many of these procedures are also very uncomfortable for the patient. Maybe they should have posters in hospitals, "life support is..." and "these procedures are..." to help educate the public. Terms like intubate and ventilate have come to sound like everyday procedures thanks to television shows like ER, Scrubs, Medical Investigation without really having an understanding of what these procedures involve. A ventilator is not just a breathing machine, it is keeping the patients lungs full of air and it cannot be taken out for a few moments or the patient may pass away. This is life support.
