Design Objectives

• Design, purchase, and implement an
  instrumentation system that will provide data to
  calculate the heat transfer rate within an
  uncertainty of 3
• Design and implement an electronic data
  acquisition system that will process the data
  from the instrumentation and output this data to
  a user interface on a PC
• Design an educational laboratory exercise

Lab Exercise Objectives

• Use the Wilson plot technique to separate pipe,
  air, and hot water resistance for natural (free)
  convection.
• Use an energy balance to validate an
  instrumentation system across a heat exchanger.
• Compare the effectiveness of parallel vs. counter
  flow.
• Compare one phase and two phase flow, and use
  Wilson plot technique to calculate heat transfer
  coefficients for hot water and steam.
• Use surface thermocouples to validate Wilson plot
  technique when calculating local heat transfer
  resistances and rates.
• Learn how to design an instrumentation system
  using uncertainty analysis.
