Hai Mr. Rudi Tua, Siang Pak,

I guess you can simulate it with hysis software, the software will make psi (pressure) output for your simulation.

But, you need more field data for this.

Why dont you just assume the power loss (that can be occured when one boiler shut down) ?

all the power generated devided by the amount of boiler. Just only for presume the simulation.

I guess how to simulate with software such as ETAP (if you take this software) will be the concern.

thanks,
