Question
i need the answer quickly
1. Sketch a diagram for the experimental apparatuses and any instrumentation and devices.
2. State any possible error source in the estimation of K value.
3. Could you suggest any improvement for the experiment.
4. If you forget to open the water supply while the apparatus is running, what will happen do you
think?.
5. Can we use the method used in this experiment to find the mass flow rate of air? If not give some
methods or instruments to determine the mass flow rate of air.
6. Could we use the method stated in this experiment to estimate the thermal conductivity of
insulation?
7. If the rod has a heat generation, then will the temperature relation be linear?
8. derive the temperature distribution within the plane wall for the case of one dimension, steady
state heat transfer without heat generation. The wall is subjected to known temperature values at
both sides as shown below:

-Plot the temperature with x using Microsoft Excel sheet and find the constants (a) and (b) using
(Trend line) property.
-Find the experimental value of K.
-Estimate the error percentage.
-Find the heat lost by compare
value heat with electric power consumed by the heating element:
