A balanced bank of delta-connected capacitors is connected in parallel with the load which complex power associated with each ph

ase of a balanced load is 146 191j kVA. The effect is to place a capacitor in parallel with the load in each phase. The line voltage at the terminals of the load thus remains at 2460 V . The circuit is operating at a frequency of 65 Hz . The capacitors are adjusted so that the magnitude of the line current feeding the parallel combination of the load and capacitor bank is at its minimum.
What is the size of each capacitor?

Answer:

77.2805 μF

Explanation:

Given data :

V = 2460 V

Q = 191  Kva

<u>Calculate  the size of Each capacitor </u>

first step : calculate for the value of Xc  

  Q = V^2/ Xc

  Xc ( capacitive reactance ) = V^2 / Q = 2460^2 / ( 191 * 10^3 ) = 31.683 Ω

Given that  1 / 2πFc = 31.683

∴ C ( size of each capacitor ) = \frac{1}{2\pi *65 *31.683}  =  77.2805 μF

Integrated circuits typically are mounted on ________, which are then plugged into the system board.
MrRa [10]

Answer:

chip carriers

Explanation:

The components of a transistor or an integrated circuit are contained on a chip carrier. It is also frequently referred to as a chip container or chip package. With the help of this packaging, the chips can be connected or plugged into a circuit board without risking damage to their delicate components. As chip carriers have shrunk in size to accommodate new technologies, the procedure of installing them has grown more complicated.

Determine the initial void ratio, the relative density and the unit weight (in pounds per cubic foot) of the specimens for each
Elina [12.6K]

The initial void ratio is the <em>parameter </em>which is used to show the structural foundations for each <em>specimen of sand </em>so that the method and speed of compression would be <em>measured</em>.

Relative density is the mass per unit volume of each specimen of sand which is <em>measured </em>and it has to do with the<em> relative ratio</em> of the density of the sand.

Unit weight is the the exact weight per cubic foot of the sand which is measured.

Please note that your question is incomplete so I gave you a general overview to help you better understand the concept

A rigid tank having 25 m3 volume initially contains air having a density of 1.25 kg/m3, then more air is supplied to the tank fr
Hoochie [10]

Answer:

\Delta m = 102.25\,kg

Explanation:

The mass inside the rigid tank before the high pressure stream enters is:

m_{o} = \rho_{air}\cdot V_{tank}

m_{o} = (1.25\,\frac{kg}{m^{3}} )\cdot (25\,m^{3})

m_{o} = 31.25\,kg

The final mass inside the rigid tank is:

m_{f} = \rho \cdot V_{tank}

m_{f} = (5.34\,\frac{kg}{m^{3}} )\cdot (25\,m^{3})

m_{f}= 133.5\,kg

The supplied air mass is:

\Delta m = m_{f}-m_{o}

\Delta m = 133.5\,kg-31.25\,kg

\Delta m = 102.25\,kg
