Answer is: 12.8 because when you multiply it by the 2nd power of 8 then the scraper equals to be 12.8 in height and that’s how much each scraper requires to operate :)

A single-phase transformer circuit feeds a motor and lighting load of 50 kilowatts. At a power factor of .8, the KVA rating of t
AveGali [126]

The KVA rating of the step down transformer at the given power factor would be 62.5 kVA.

<h3>What is power factor of a transformer?</h3>

Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA).

PF = working power / apparent power

PF =  kW/kVA

kVA = kW/PF

kVA = 50 kW/0.8

kVA = 62.5 kVA

Thus, the KVA rating of the step down transformer at the given power factor would be 62.5 kVA.

Calculate the fraction of lattice sites that are Schottky defects for cesium chloride at 573 oC (this temperature is below the m
inn [45]

Answer:

2.9\times 10^{-6}

Explanation:

Q_s = Energy for defect formation = 1.86 eV

T = Temperature = 573^{\circ}\text{C}=573+273.15=846.15\ \text{K}

k = Boltzmann constant = 8.62\times 10^{-5}\ \text{eV/K}

The fraction of lattice sites that are Schottky defects is given by

\dfrac{N_s}{N}=e^{-\dfrac{Q_s}{2kt}}\\\Rightarrow \dfrac{N_s}{N}=e^{-\dfrac{1.86}{2\times 8.62\times 10^{-5}\times 846.15}}\\\Rightarrow \dfrac{N_s}{N}=2.9\times 10^{-6}

The required ratio is 2.9\times 10^{-6}.
