Hi,

I am a mechanical engineering student, and my group and I were given this problem:

Emergency Steam Dump System An nuclear power plant has 4 steam
generators that produce 1000 kg/s steam at 50 bar absolute and
saturated under normal operating conditions. However under emergency
conditions, where the turbines cannot accept steam (turbine trip), 60%
of the steam must bypass the turbines and be dumped directly to the
condensers through a 50 m long piping system. The condensers are at a
pressure of 4 kPa absolute. Design the steam dump line and as much as
possible avoid pipeline vibration which is typical of these
installations.

Anybody could help us with this? We haven't learned compressible flow yet, and our prof. just expects us to learn it on our own. He told us to read about Fanno Flow... I kinda understand it, but not quite. Could anybody give me basic equations to work with (I've been reading a textbook, and with all the derivations, it's hard to tell what I should be using). Any help of any kind would be greatly apprciated.

Thanks,

S
