January 27, 2007, 23:03	very high thermal efficiency	#1
carno Guest Posts: n/a	Hi folks, I have done a analysis of 80000 rpm centrifugal blower. Problem is with compressible air. Bcs are pr-pr at inlet and outlet. Now problem is that we are getting very high 90+% thermal efficiency, i.e. hirdly 20deg rise in temperature with pressure ratio of 1.2. We are getting mechanical efficiency (power consumption) inline with test results. What could be the reason of abnormally low temperature rise?
