00002: WHOLE SYSTEME TEST

Step	Step Description	Expected Result	Result
Precondition	System is off
open the valves V1 and V1	open the valves V1 and V1 from the GUI	the valve v1 anv d v2 are open and enable to let the nitrogene gas pass	positive result
WASH THE SYSTEM WITH NITROGENE	Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank	-one can see that there is nitrogene exit from the gas outlets	positive
Switch on the system	Turn off the nitrogene Turn on the systeme from the GUI	THE SYSTEM IS GENERATING hydrogene and oxygene	we turned on the systeme but no hydrogene or oxygene generation
Burn the hydrogene	Turn on the transformator	The Hidrogene is burning	negative since no hydrogene generated
Switch off the system.	Switch off the system from thGUI Switch off the transformator	The system goes down.	positive
WASH THE SYSTEM WITH NITROGENE	Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank	All the hydrogene existing in the pipe systeme exeit	positive
Postcondition	systeme is off

turning on the systeme through the GUI after nitrogene purging for more than 10 minutes

We watched everything through 2 cameras and found that nothing had happened.
This could be seen by the fact that no current was withdrawn from the power supply and that no bubbles formed in the 2 containers.

Analysis of the test results :

the reason why no hydrogene was generated is that the KOH concontration was not high enough .

the desired concentration is 5 to 7 molar = 280,528 g/L

We had entered far too little KOH, which left the contagtivity of the solution close to zero.

what we have to do :

Increase the concetratiom of the KOH .
