Question
Fans/Pumps Flowrate vs. Pressure Drop: Given the following 36mm x 36mm performance (?P vs Q ) below, plot the expected air flowrate ( P[inH20] vs. CFM) if two of these fans are put a) in series and b) in parallel.
2) Fans/Pumps Flowrate vs. Pressure Drop: Given the following 36mm x 36mm performance (AP vs Q) below, plot the expected air flowrate PlinH20] vs. CFM) if two of these fans are put a) in series and b) in parallel.

a) fans in series.
When the two similar pumps/fans are arranged in series, the volume flow rate is equal to that of a single pump and the pressure raise P is twice that of a single pump. Accoedingly the data are given below.
b) Fans/Pumps in parallel.
When two pumps/fans are arranged in parallel, then the pressure raise will be equal to that of a single pump and the air flow rate will be equal to the twice that of a single pump.
