A balanceed three-phase load of 15 MA with a lagging load factor of 0.85 is supplied by a 115KV subtransmission line. if the line impedance is 50+j100Ohm per phase, determine the following: (a) The line current of the load
Consider a 15.0 mL sample of a ternary mixture composed of 25% (by volume) octane, 35% chloroform and 40% 2-propanol. Use the following information to convert volume composition to molar composition:
Phenolphthalein is an acid base indicator. What color does it possess in the presence of excess hydrogen (i.e., hydronium) ions?
A balacnced, three-phase, delta-connected load is supplied by a balanced, three-phase, wye-connected source over a balanced three-phase line. the source voltages are in abc phase sequence in which Van is 19.94<0 KV.
Three -phase motor is connected to a three-phase power source that has an abc phase sequence. the first load is a wye-connected, three-phase motor withdrawing a line current of 20A at a 0.8 lagging power factor.
A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL.
