Procedure

Follow these Steps:

1. Make the set-up as shown in Figure.

2. Fill the steam generator with water up to about 2/3rd height. Keep it on a Hot plate and switch ‘ON’ the Hot plate then steam is being formed in the steam generator. Pass a steady current of steam from the boiler through the rubber tube into the steam chamber to heat the end ‘A’. Place a tray below the outlet 0 of the stem chamber to collect the condensed water.

3. Allow the water to flow through the copper coil by adjusting the height of constant level tank or by the use of a pinch cock adjust the rate of flow of water through copper coil so that water comes out as a trickle through the outlet end.

4. Insert all the 04 thermometers in their respective places as shown in Figure.

5. Attain the steady state i.e. reading of temperature of all the four thermometers should be constant and there should not be any further increase in temperature.

6. After steady state when the readings of all the four thermometers remain constant for nearly 05 minutes, note the thermometer.

7. Now place a clean and dry measuring cylinder below the outlet of the copper coil and collect the water flown for a known time. Calculate the mass of water flowing per second.

8. Repeat the above procedure 3 to 4 times.

9. Measure the distance between the two fixed point where the thermometer T1 and T2 inserted.

10. Measure the diameter of the rod and calculate the value of K using formula as given above.

11. Calculate mean value of mass of water collected per second.

12. Measure steady state temperatures.
