Your captured sample will be flow rate x time. Your bottle size is the upper limit of the amount you can capture (any more than that amount and the bottle will explode and you won't capture anything). You must allow for reduced flow rate as the pressure rises in the bottle.

Why does coolant bubble back from radiator into plastic coolant container on d22 nissan navara


If it is a constant bubbling while running and at that same time the engine is not overheated,you may need a head gasket replacement.

What is titration


Titration, also known as titrimetry,[1] is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. Since volume measurements play a key role in titration, it is also known as volumetric analysis. A reagent, called the titrant or titrator[2] is prepared as a standard solution. A known concentration and volume of titrant reacts with a solution of analyte or titrand[3] to determine concentration. The volume of titrant reacted is called titration volume

What is a flow meter?


Wikipedia: Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive-displacement flow meters accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow measurement methods rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.

What is a venturi valve?


Hi maggiezmart
A venturi valve is a valve that has a reduced size in the middle thus causing a low pressure in the middle of the valve to create a vacuum to pull liquids/gases into the flow stream.

How to find pH


Do you have the concentration? if YES, you CALCULATE the pH with the relation
pH=-log(c) where c is the value of concentration in mol/L.
ex: c= 3.57x10^(-6)
pH: (-) [LOG] 3.57 [2nd][EE] [(-)] 6 [ ) ]
Here you have 2 change sign key press [(-)]

If you have the pH, and want to calculate the concentration that yields that value of the pH you proceed as follows
c= 10^(-pH)
Ex pH=8.23
c: [2nd][LOG] [(-) 8.23 [)]

Here is a screen capture to show you both calculations

Yes it is normal just no hot air


1. When setting the temperature to MAX, blower level to FULL and outside air Vent CLOSED, no hot air comes out after 2-5 minutes?
If YES, when did you last flushed your radiator and is it full?
2. if more than 5 years ago, flush radiator system, instructions are usually in Owners manual. Use a bottle of Radiator cleaner, run egine hot for about 10-15 minutes, carefully open petcock in bottom of radiator to flush out radiator, WARNING, careful as flushed coolant would be boiling hot. As sson petcock is open and water start to flow out, carefully open radiator cap to enhance flushing flow. Use garden hose to fill radiator while flushing until water coming out from petcock is cold and clear.
Once clear, start engine, turn heter full and blower full blast and keep hose in radiator flowing full, leave petcock open until clear water flows out again. Once clear waters comes out, turn off engine,turn off garden hose and let water drain empty radiator. Once it stops flowing out, close petcock snug and put radiator cap on, pull off radiator coolant catch bottle, clean bottle for any debris and dirt. Drain any water, leave bottle empty and put it back onto its place.
3. Fill radiator with 1 gallon (4L) of concentrated coolant, top up radiator until full, fill catch bottle with concentrated coolant, start engine and keep it overflowing until no bubbles comes out and the radiator is fully hot. Once it is flowing good, close and connect everything. Drive with it and keep catch bottle filled as necessarry.
Good luck. Give as vote and good comment if this advise solve youor problem. Thank you.

How do I calculate: What is the [H3O+] of a solution with a pH of 4.5 on the TI-83 Plus


If you have the pH, and want to calculate the concentration that yields that value of the pH, you proceed as follows
c[H3O ] = 10^(-pH)
Ex pH=8.23
c[H3O ] : [2nd][LOG] [(-)] 8.23 [)] where
[(-)] is the change sign key.

Here is a screen capture to show you how to calculate the pH (first example) and the concentration (2nd example)

Loosing water from over flow bottle once a week


It may be that you have bad head gaskets. Internal gases can pressurize the cooling system and push water from the bottle. It is worth the check, to be sure.
