Mechanical Engineering

1. For airflow through a fan, the mechanical energy balance withfan work along with conservation of mass are:

-W(dot)fan=sum((m(dot)_exit)*(e_exit)) -sum((m(dot)_inlet)*(e_inlet))

so...

0=sum(m(dot)_exit) - sum(m(dot)_inlet)

Using the mechanical energy balance and conservation of mass,show that the theoretical fan power added to the air is flow ratemultiplied by the pressure rise:

W(dot)fan=?*?*P
