3.3.4 Operating Procedures for Humidification System 
Every morning: 
Disconnect the graduated cylinder from its tubing (directly below the needle valve at the bottom 
of the fitting that connects the tubing to the solenoid). Some water may drip out of the 
needle valve. 
Take the graduated cylinder to the sink in the main lab. 
Open the needle valve all the way and fill the graduated cylinder with water. Allow the cylinder 
to drain and repeat until water flows freely through the needle valve. 
Close the needle valve all the way and fill the graduated cylinder with water to check for leaks. If 
there is a leak, patch it with the sealer. 
Open the valve until there is a very slow drip, about one drip every five seconds. 
Empty the cylinder and refill to 30 mL. Check if there is a slow drip with the cylinder filled to 30 
mL. If there is, fill the cylinder to about 90mL. If there is not, open the valve until it starts 
dripping slowly. Refill the cylinder and repeat steps five and six until a steady flow is 
achieved at both 30 and 90 mL. 
Reattach the cylinder to the calorimeter. Repeat steps one through seven for all three 
calorimeters. 
Turn the solenoids on and off 10 times. Turn the solenoids on and be sure that water is flowing 
out of the needle valves. If no water is flowing out, turn the solenoids on and off 10 more 
times. If water still does not flow, open the needle valve four turns. If water still does not 
flow out, seek assistance. 
Record the current water volume within the cylinders. Make sure the cylinder is almost vertical. 
Record the water volume at the end of each run.
