How much sense will it make to specify a multiphase pump for crude oil with GOR of 20
and a paltry flow rate of 4000 Bbl/day?

i would like to modify an induction motor from three phase to multiphase. that means i have to change to windings configuration since the amount of the current flows will also change too. Does anybody knows the relations between the amount of the current flows and the diameter of the windings? or

I have to install a small cooling tower for an extrusion process, but the industrial facility has an arch roof covering the wole area. How can the efficiency of the tower affected if installing it behind the roof instead on an open area?
Hello,
I need of a small, submersible load cell, that can be used in tension (threaded on one end, and can be bolted to a surface on another) that only has a capacity of 2lbs. I also need something with the amplifier built in or one that I can purchase with the load cell so that I do not ha
I have a PTO driven 25 KW generator. Normally it is recommended to use a 50 hp tractor to drive it to get full power (2 hp x each KW.) I have used a 40 hp tractor to run a 7.5 hp submersible pump on a fish farm with this generator. I am looking at a 34 hp tractor and wonder how much output I coul

hello everyone,
I have been wondering since years as to why a railway electric engine outer body does not produce an electric shock when the entire body is metallic carrying 25 KV(in India).
Thanx in advance

Why is the excitation of a generator (not a generator transformer unit) switched ON at near to rated speed?
For example, the excitation of 750rpm rated speed generator is switched ON at 560rpm. Switching ON of the excitation a very low speed would have overloaded the excitation system and
Why is the lug inner diameter more than the cable core diameter?
I have a 500sq.mm single core stranded aluminium cable whose core diameter is 26.4sq.mm. Corresponding copper lug inner diameter is 30mm. Ofcourse, the cable inner diameter should be slightly more than cable core diameter so tha
