U22 Scientific Principles Assignment A
| Learning Outcomes |
| This assignment will assess learning outcomes LO1 and LO2 for which you will be expected to calculate energy transfer rates in different building services contexts and evaluate conditions of static and dynamic fluid flow to determine energy loss. LO1 Calculate energy transfer rates in different building services contexts LO2 Evaluate conditions of static and dynamic fluid flow to determine energy loss |
| Assignment Scenario: |
Calculate energy transfer rates in different building services contexts.
Your current role as a technical design engineer will help to build a successful team within your organisation. Your line manager will require a technical memorandum of supporting material to distribute to the new members of the team to help develop their understanding of the mechanisms of heat transfer related to building services engineering.
The line manager suggests that your technical memorandum specifically covers:
A description of how conduction, convection and radiation contribute to heat transfer in composite materials with illustrated examples of each mechanism within different forms of composite structures.
The method used to determine the risk of interstitial condensation in multi-leaf plane structures with illustrations to help analyse how moisture moves through the layers of the structure and where it might condense.
Calculate conduction rates used in various building services plant and equipment, to include the variables used to perform these calculations.
In fluid systems, discuss the types of fluid flow, explain what is meant by ‘fluid energy’ and the potential mechanisms of energy losses in BSE systems. Show how to calculate the energy loss in pipe and duct networks, using appropriate formulae for a BSE applications.
