Calculation of fan total pressure
Thread Content
To enable the fan to supply air at a pressure of 0.08 MPa to the engine’s intake, the total pressure from the fan outlet to the engine inlet is 0.01 MPA; there is also a filter at the fan inlet, contributing another 0.01 MPA to the total pressure. So is the total pressure of the fan 0.08+0.01+0.01=0.1MPA? The above data are example data.
The total pressure from the fan outlet to the engine inlet – there is total pressure at the fan inlet due to filters and other elements; how can these values be considered known parameters? How did you calculate them? You’ve calculated it to be the resistance loss, right.
The two 0.01 values you mentioned are likely both estimated resistances. I’m also confused about fans. Total outlet pressure – Total inlet pressure = Fan total pressure. Total pressure = Static pressure + Dynamic pressure
