A generating station consists of two 100 MVA generators with 6%

reactance each and one 150 MVA generator with 8% reactance as shown

in Figure below. These generators are connected to a common bus bar

from which loads are taken through a number of 50 MVA, step up

transformers each having 5% reactance. Compute the rating of circuit

breaker on (i) low voltage side and (ii) on high voltage side.

¨For simplicity, take *n *= 2.0 and use the value of *f *for* *complete turbulence, as given by Eq. (8.54).

¨All pipes are cast iron, and are at the same elevation. For initial flows, assume only values of 30,15, and 0 L/s (the zeros in *dg *and *fh). *

¨If the pressure head at *a *is 40 m, find the pressure head at *d *(which might represent a fire demand, for example) neglecting velocity heads.
