1.in a couple pipe heat exchanger,Which configuration is more efficient at transferring heat, counter current or parallel flow?2.what is the effect of complete or incomplete agitation on heat transfer coefficient in agitated tanks?
1. You will transfer more heat with counter current flow, which is more efficient. 2. With more aggitation a greater volume of fluid will be exposed to the transfer surfaces and consequently more heat will pass. Then the heat transfer coefficient will be greater.
