Micro hydro system?

I want build a micro hydro system that using water jet as prime mover. The spec of water jet is 40 bar pressure and 17 liter/minutes. Prediction of this system is can produce 1 to 1.5 kw output from generator. Do you think this system can produce this output? With water jet that i use, how much you think i can get RPM(revulation per min) at turbine.
