Designing A Thermodynamics Experiment

The final design was very simple. It consisted of a stainless steel tank and a tank cover that we made out of a piece of carton. All of the equipments that were used (thermometer, pump, heater, inlet and outlet pipes) had it place on the cover

The equipments we used had the following restrictions on its usage:

1. The maximum pressure for the pump is 40psi and the normal operation pressure is 18psi.

2. The pump provides a steady flow rate that ranges between .4 to 987 ml/min depending of the tubing that is being used.

3. The maximum section left that the pump provides with water is 29ft (8.8m).

4. The electric current needed to operate the pump is 2 amps.

5. The angular velocity of the pump is 58rpm.

1. This heater can only be used for heating water; it cannot be used to heat other liquids.

2. The round base should be always covered with water.

3. The heater should not be operated with out water; it will disconnect with in 2-3 minutes if that was done.

4. Allow 10 minutes per gallon of water to heat.

5. The electric current needed to operate the heater is 10amps.

6. If the water is heated to the desired temperature disconnect the heater.

But when I started making the holes in the insulation there were many problems involving that. Chose the appropriate tubing for the desired flow rate. 5in to a height just below but not toughing the bottom of the black handle. Using a pencil draw a circle for each diameter that has been recorded in step 4 on the piece of carton that is going to be used as a cover. After finishing the experiments make sure that all the equipment are dry and properly stored in their boxes. To find the value of Cp we need to use the constants value given in the course text book in appendix B table B. Cut these circles using a cutting knife. Place all the equipment provided (thermometer, pump inlet pipe, heater, and the pipe of the flow rate coming in) on the cover each one in the hole that was made for it. 24KJ/sec

And since we don¡¦t know the exact flow rate we can not add the work term to the enthalpy term. A recommendation to avoid this miss is to use a glass cover for the tank.
