why does my fan pressure difference so small?

Question asked by Billy Nandika Infantuzziano on Jul 1, 2020

Hi, i'm a student and i'm working on my final project about fan performance using flow simulation.

The installation of fan performance test that i made is bassed on AMCA 210 standard, my boundary condition is environmental pressure on both side (inlet & outlet)

The pressure difference in the simulation results is very small, causing a small efficiency. 

Does anyone know the cause?

and why the result of motor power (power input) so far from the design power (74 W)?


please help:( your help means a lot to me
