Two balanced, wye-connected, three-phase loads are in parallel across a balanced, three-phase 60- Hz, 208-V supply. The first load takes 12 kW at 0.6 power factor lagging, and the second load takes 15 kVA at 0.8 power factor lagging.
(a) Draw the power triangle for each load and for the combination.
(b) What is the total kVA supplied?
(c) Find the supply power factor, and specify whether lagging or leading.
(d) Compute the magnitude of the current drawn by each load and drawn from the supply.
(e) If wye-connected capacitors are placed in parallel with the two loads in order to improve the supply power factor, determine the value of capacitance in farads in each phase needed to bring the overall power factor to unity.
Crude dichlorobenzene is pumped from a storage tank to a distillation column. The tank is blanketed with nitrogen and the pressure above the liquid surface is held constant at 0.1 bar gauge pressure. The minimum depth of liquid in the tank is 1 m.
Reconnected in Y-?, with the same high tension voltage supplied and the same load resistors connected?
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
oleum or fuming sulfuric acid available commercially in concentrations ranging from 20 to 99.9 sulfur trioxide. a.
Analyze the difference between visual pursuit tracking and visual scanning in terms of the oculomotor mechanisms that underlie these two activities.
For the numerical values I = 10 A,N = 500 turns, g = 5 mm, a = 20 mm, b = 2 mm, and l = 40 mm, find the magnitude of the force. Assume infinite permeability of the core and neglect leakage.
What is the empirical formula of this compound and does this compound behave as an ideal gas
A company is considering the purchase and installation of a pump which will deliver oil at a faster rate than the pump already in use. The purchase and installation of the larger pump will require an immediate layout of $1600, but it will recover ..
A storage tank is purged continuously with a stream of nitrogen. The purge stream leaving the tank is saturated with the product stored in the tank.
From a three-phase, 60-Hz system, through a motor-generator set consisting of two directly coupled synchronous machines, electric power is supplied to a three-phase, 50-Hz system.
Determine the speed of prime mover of the generator.
Find the ratio of the speed of the generator to the speed of the motor when the total line current is 80 A in both cases.
