A load is connected on the line having 1-0, 125 MW at 215
KV with 100% power factor. Line series impedance per unit
length z=0.1603 + j0.8277 22/mile, shunt admittance per unit
length y = j5.105x 10-06 mho/mile).
Now find the voltage, current and power at the sending end
and the voltage regulation of the line if the length of the line
is-
a.
10 miles, or
230 miles

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
