EES download version and General Compressor Query

[StevenKatzeff]

Hi,

I have been using Engineering Equation Solver for my dissertation, but the academic version supplied by my University always seems to be expired. Can anybody help me find a site I can download the academic version from?

Secondly, does anybody know what the typical isentropic efficiency of a large Howden pump used for an ice making plant at a mine. The mine has closed down and Howden South Africa no longer deals with pumps. It was a screw pump with an electric power rating of 1350 kW, used to produce 1000 tons of ice per day.
Thanks

it's not just "download" you will need to pay:
