A balanced delta-connected load has a per-phase impedance of 45 60° Ω. It is connected to a three-phase, 208-V, 60-Hz supply by a three phase feeder that has a per-phase impedance of 1.2 + j1.6 Ω.
(a) Determine the line-to-line voltage at the load terminals.
(b) If a delta-connected capacitor bank, with a per-phase reactance of 60 Ω, is connected in parallel with the load at its terminals, compute the resulting line-to-line voltage at the load terminals.
Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
Two coupled synchronous machines are used as a motor-generator set to link a 25-Hz system to a 60-Hz system. Find the three highest speeds at which this linkage would be possible.
Find reading of oil-mercury differential manometer.
When the transformer is delivering rated kVA to a load at rated secondary voltage and a 0.85 lagging power factor, find the percent voltage regulation and the efficiency of the transformer.
mole of oxygen in the exhaust gas per unit weight of fuel. e- mole of water vapour in exhaust gas per unit weight of fuel.
It will dissolve, however, in aqua regia, a mixture of the two concentrated acids. The products of the reaction are the AuCl46- ion and gaseous NO. Write a balanced equation for the dissolution of gold in aqua regia.
What force must the biceps generate to hold the forearm in static equilibrium?
A vapour stream that is 65 mole% styrene and 35 mole% toluene is in equilibrium with a liquid mixture of the same two species. The pressure in the system is 20 kPa. Use Raoult's law to estimate the composition of the liquid and the system temperat..
The reflux ratio is set at 4.0:1. Calculate the kg mol/h distillate D and bottoms W and their compositions. Also, calculate the number of theoretical plates required.
Monczka-Trent has two options: (1) its standard 2-day shipment or (2) a subcontractor who will team drive overnight with an effective delivery of 1 day. The extra driver costs $175. Handfields's holding cost is 35% annually for this kind of inventory..
Aniline is produced by the hydrogenation of nitrobenzene. The reaction takes place in a fluidized bed reactor operating at 270 °C and 20 bar. The excess heat of reaction is removed by a heat transfer fluid passing through tubes in the fluidized be..
A 100-kW, 250-V shunt generator has an armature-circuit resistance of 0.05 Ω and a field circuit resistance of 60 Ω. With the generator operating at rated voltage,
