A balanced electrical industrial plant load of 9.8 MW with 0.8 lagging power factor is supplied by a three-phase 60-Hz system having a maximum rating (load-carrying capacity) of 660 A at 11 kV (line-to-line voltage).
(a) Determine the apparent power and the reactive power drawn by the load.
(b) Additional equipment, consisting of a load of 1.5 MW and 0.7 MVAR lagging, is to be installed in the plant. Compute the minimum rating in MVA of the power factor correction capacitor that must be installed if the rating of the line is not to be exceeded. Find the system power factor.
(c) If the capacitor, consisting of three equal sections, is connected in delta across the supply lines, calculate the capacitance required in each section.
A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second. Steam mixes with additional steam that has been throttled from a pressure of 2000Kpa to a pressure of 800Kpa which enters from a branch pipe. If t..
Discuss the characteristics of this microenvironment.
Prepare a piping diagram and calculate the pipe size as well as the required power of the pump. You need to specify the type of fittings and the pipe material for your calculations.
At full load, find the speed of (i) the rotor field with respect to the rotor, (ii) the rotor field with respect to the stator, and (iii) the rotor field with respect to the stator field.
Discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and pressure-specific volume diagrams for one- component systems. Use the example of a mixture of ethane and heptane to illustrate your..
Wet air containing 4.0mole% water vapor is passed through a column of calcium chloride pellets. The pellets adsorb 97.0% of the water and none of the other constituents of the air. The column packing was initially dry and had a mass of 3.40kg, fol..
Take the saturation temperature of n-propanol at 2.1 bar as 118oC. The otherphysical properties required can be found in the literature, or estimated.
determine the minimum service life allowable for the facilities at the distant location for this alternative to meet the required incremental return. The salvage value should be assumed to be zero, and straight-line depreciation accounting may be ..
A plant has a batch of 100 kmol of a liquid mixture containing 20 mol% benzene and 80 mol% chlorobenzene. It is desired to rectify this mixture at 1 atm to obtain bottoms containing only 0.1 mol% benzene. The relative volatility may be assumed con..
For a feed rate 2000 kg/h of solution, composition 30% w/w MEK, determine the number of stages required to recover 95% of the dissolved MEK, using 700 kg/h TCE, with countercurrent flow. Tie-line data for the system MEK-water-TCE percentages w/w, ..
Should the lease-and-flood arrangement be accepted? How should this proposal be presented to the company board of directors who understand and make it a policy to evaluate by discounted-cash-flow rate of return?
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.
