but if i increased the cross sectional area to be twice. while one pump runing the area will be very wide which will reduce the head and increase the flow and increaing the power consumed

Thanks for your kind replay but now in design stage how could I reach douple flow while both pump runing by increasing pipes dia ??

in college days it is known that if you want double pressure install the pumps in series if you need double flow install the pumps parallel. but in actual field i have two pumps installed in parallel in Sewer Pump Station one as on duty and the second one is assist. but while both pumps running...

i have one problem for pumping treated water in line 4 bars there is no suitable pump with this suitable head so what is the procedures for series instlations ?

thank u for ur answer but this link is speake about changing rpms it is available to change the pump head by change pump capacity with constant RPM and how ?

i need some help becoase i become confused according to pump characteristic curve if the flow rate increased the head will decreased the question is how i can increase the flow rate and what is the relation of RPM with head and flow rate

I neeed help in terbomachinary ! I need answer to a specific quistion . Why we use backward blade in impeller design for high speed compressors ??

pump storage plants ( reversable turbine pump ) so after i write my enquiry i still search so i find some thing about it so it is an educational equipment used to simiulate reverse turbine pump eas.asu.edu/~holbert/eee463/pumpedstorage.html this site show how reverse turbine pump working...
