Operate the change over switch of temperature indicator gently from one position to other, i. Never exceed 80 W power. Compare the experimentally obtained values with the theoretically predictions of the cor- relations 4 and 5. All the fluid properties are to be evaluated at mean film temperature. For this experiment all the temperatures represent the measured values.

The thermocouples had a resolution of 0. These quantities are used to calculate the uncertainties related to these experiments. To obtain the uncertainty from the accuracy of the instruments a mathematical formula is used to calculate how these individual errors compound to give the net error in a calculation.
The experiment has been designed such that the resistance to heat conduction inside each specimen is much smaller than the external convective resistance. So, the internal temperature variation inside the solid test specimen will be small. The specimen cools by convection and radiation. Thus, in Eq. Using this average temperature and the cooling rate from Eq.
Equation 10 gives the value of measured heat transfer coefficient including radiatiative heat transfer coefficient. The error can be calculated by taking difference of measured values and the predicted or theoretical calculated values.
Figure 6. The comparison of average heat transfer coefficient is also made with predicted values by using correlation 4 and 5. It is found that the predicted values are somewhat less than the experimental values due to heat loss by radiation.
Furthermore, there are two subtypes of convection: forced and natural convection. Radiation heat transfer is the transfer of heat by electromagnetic radiation. Energy transfer by radiation is at a maximum when the two surfaces exchanging energy are separated by a vacuum.
Sukhatme, Dr. Holman, J. Cengel, Y. Incropera, F. Transfer Coeff. Method Solid shapes of different size, form and material of construction are allowed to stabilize at room temperature then dropped into a bath of hot water. Ensure that the lid of the hot water bath is fitted and the inlet at the base of the flow duct is connected to the outlet of the circulating pump using flexible tubing.
Ensure that the drain valve on the water bath is closed then fill the bath with clean water until the level is coincident with the centre of the holes in the vertical flow duct as shown in the diagram below. Connect the power lead from the water bath terminated at the connection box alongside the heating tank to an electrical supply. Ensure that the service unit is connected to an electrical supply.
Select Exercise A. Change the settings if required.
Place the various shapes in a suitable location where the metal bodies can stabilize at room temperature. Always pick up the metal shapes via the insulated rod. Heat transferred to the shape by holding in the hand will delay the stabilization of the shape at a uniform temperature.
Note: Since the water bath will take approximately 40 minute to heat to the required temperature it is suggested that this is switched on immediately as described in the Procedure section. This condition, referred to as unsteady-state, exists when a solid shape is immersed in the hot water and continues until the whole of the shape reaches equilibrium with the temperature of the water.
When the step change is applied a temperature gradient exists between the surface of the shape at the water temperature and the centre of the shape which is at ambient temperature. Heat flows by conduction through the shape until the whole of the shape is at the same temperature as the water. Note: The plots of temperature versus time obtained in this exercise can be used in later exercises to perform a quantitative analysis of the unsteady state heat transfer related to the size, form and conductivity of the solid shape.
Procedure Refer to the Operation section if you need details of the instrumentation and how to operate it. Switch on the front Mains switch if the panel meters do not illuminate check the RCD and any other circuit breakers at the rear of the service unit, all switches at the rear should be up. Check that the water heater is filled with water then switch on the electrical supply to the water heater switch on the RCD which is located on the connection box adjacent to the water heater.
Ensure that the red light is illuminated on the water heater, indicating that electrical power is connected to the unit. Adjust the thermostat on the water heater to setting '4' and check that the red light is illuminated indicating that power is connected to the heating element. Set the voltage to the circulating pump to 12 Volts, using the control box on the mimic diagram software screen. Allow the temperature of the water to stabilize monitor the changing temperature T1 on the software screen.
If outside this range adjust the thermostat and monitor T1 until the temperature is satisfactory. Attach the large brass cylinder to the shape holder insert the insulated rod into the holder and secure using the transverse pin but do not hold the metal shape or subject it to a change in temperature. Check that the thermocouple wire is located in the slot at the top of the shape holder. Check that the temperature of the shape has stabilized same as air temperature T2.
Allow the temperature of the shape to stabilise at the hot water temperature monitor the changing temperature T3 on the mimic diagram software screen. When temperature T3 has stabilized, select the icon to end data logging. Select the icon to create a new results sheet. Switch on the electrical supply to the water bath to allow the thermostat to maintain the water temperature.
Remove the large brass cylinder from the shape holder then fit the stainless steel cylinder. Repeat the above procedure to obtain the transient response for the stainless steel cylinder. Remember to create a new results sheet at the end, ready for the next set of results. Remove the stainless steel cylinder from the shape holder then fit the small brass cylinder. Repeat the above procedure to obtain the transient response for the small brass cylinder.
If time permits the response of the other shapes can be determined using the same procedure as above. Results and Calculations The transient behavior of the various shapes is best analysed graphically using graphs of temperature versus time which you have obtained.
Graphs can be plotted from the Graph screen of the software. Select the graph screen using the icon, then select the icon to open the graph configuration screen. The available results are listed on the left. The graph may be printed to a printer if one is available by selecting the icon. Using the large brass cylinder as a reference, the small brass cylinder stabilizes faster because the distance between the centre and the surface of the cylinder is considerably reduced.

These findings are repeated if the spheres or slabs of different material are compared. Conclusion You have observed how, in a solid shape, temperature changes with time and position while heat flows from the hot boundary to heat the cooler material inside of the shape.
This condition of unsteady-state heat transfer exists until the temperature is constant throughout the shape; no temperature gradient exists within the shape when a condition of steady-state is achieved.
The time taken for the temperature to stabilise at the centre of the shape depends on the size, form and the material of the solid shape.Heat transfer, j P.
