Flat plate heat exchanger - Hand calculations help

AI Thread Summary
Designing a flat plate heat exchanger requires understanding the LMTD and E-NTU methods for hand calculations, along with determining key parameters like area and number of plates. To effectively perform these calculations, it's essential to know the temperatures of the fluid being cooled and the coolant, as well as the specific heat of the coolant. Resources such as product datasheets and detailed design documents can provide valuable guidance. Utilizing these references will help streamline the design process and meet project deadlines. Accurate calculations are crucial for optimal heat exchanger performance.

I am designing a flat plate heat exchanger for a project and I am not sure where to start with the hand calculations, specifically the LMTD and E-NTU methods, also how to work out the parameters which i will need to complete these methods such as area and number of plates. My deadline is soon, any help is much appreciated.

Perhaps you could begin by giving us a bit more information. ie. the temperatures involved (temperature of the thing being cooled and the initial temperature of the coolant - presumably air), and the specific heat of the coolant.

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
