A balanced three phase source is supplying a balanced three phase load through a transmission line with impedance of 10+j30 ohm per phase. Load is consuming 300 MW at power factor of 0.8 lagging. Load voltage (line-line) is held constant at kV. Frequency is 60 Hz. 1. Find the real power lost in the line. 2. By adding capacitors power factor is improved to one (unity power factor) find the real power lost in the line.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
