Heat transfer in turbulent flow

1
Heat transfer in turbulent flow

• CL - 232

2
Aim

• To determine
• the overall heat transfer coefficient
• the individual film transfer coefficient
  
• and verify Dittus-Boelter equation

3
Apparatus

• Double pipe heat exchanger
• Stainless steel tank
• Circulation pump for hot cold fluid

4
Procedure

• Switch on the heater of hot fluid tank
• Keep the flow rate of cold fluid constant
• Adjust the flow rate of hot fluid
• Once steady state is reached note down the inlet
  and outlet temperatures of hot and cold fluid.
• Repeat the experiment for at least six different
  flow rates of hot fluid.

5
Theory

• Overall resistance sum of resistances in series
• Dittus-Boelter equation
