I'm trying to calculate the power required from forced induction with this equation;

W˙=m˙CpT1ηc⎡⎣(P2P1)(γ−1γ)−1⎤⎦

However I seem to be getting rather low results for work ~0.8W I have done my calculations in this spreadsheet. Any ideas where I've went wrong?

thanks

Note the file is .xls not .xlsx I had to change it to upload

File doesn't open for me. Please try to repost. Others have posted .xlsx files before.

You can open the original file if you change the extension manually. Never to worry I have worked out how to save as xlsx. Missed out a factor of 2 first time round (forgot about it being 4 stroke). I still seem to be a factor of 1000 or so out. I have ~0.4w

Do you have a source for the equation in the OP?
