. Calculate the average power in kW that can be generated in a hydro-electric from the following data Catchment area = 5×109 m²; Mean head; H = 30 m; Annual rainfall; F = 1.25 m; Yield factor; K=80%, noveall =70% If the load factor is 40%; what is the rating of generators installed

Two generators are supplying a load. Both the generators have a no-load frequency of61.5 Hz and the slope sp of 1 MW/HZ. If they are supplying a real load of 2.0 MW at 0.8 pflagging, what would be the system frequency and power sharing between two generators?What measures can be taken to make the frequency 60 HZ. If an additional 1.0 MW load isconnected to the existing one what would the system frequency be.

A 60-Hz, single-phase power line and a telephone line are parallel to each other as shown in the following figure. The telephone line is symmetrically positioned directly below phase b. The power line carries an rms current of 226 A. Assume zero current flows in the ungrounded telephone wires. Find the magnitude of the voltage per Km induced in the telephone line. 5 m 3 m d 2*mO
