Hello everyone,
I am trying to simulate Earth tubes for pre-cooling using the EnergyPlus software. Basically a fan will be used to circulate ambient air through an underground horizontal pipe.
The software requires an input field of "Fan Pressure Rise" which I am guessing is the pressure that is created by the fan to force air through the pipe.
My question is, how can I calculate the pressure that needs to be generated to make the air flow through the pipe?
System specs are:
pipe length = 50m
diameter (internal) = 0.3m
velocity = 2 m/s
volume flow rate = 0.14m^3/s
Thanks.
