Introduction
1. Objective of Experiment
- Calculate Coefficient of Heat Transfer by theoretical method and using Nusselt number Equations.
- Compare and analyze the values derived from each methods.

<중 략>

2. Procedure
1) The individual heater (diameter 10mm) is inserted in the duct above the fan.
2) The temperature of the air is measured at bottom of the duct below the fan
3) The fan is switched on, then the power for the heater is set on the control and display unit. Once the heater is switched on, the temperature at the heater will increase.
4) The measurement can be started when the temperature no longer changes.
5) The flow velocity through the flow nozzle at the inlet is determined. In order to calculate the velocity, a pressure is measured with the adjustable flap opened partly.
6) The value for the coefficient of heat transfer determined experimentally is compared with the calculated value
7) Check the temperature of air and wall.
8) Determine the convection coefficient from the experimental observations.
