Answer:
The phase current in each line conductor are;
Explanation:
Given the following data;
Red phase = 24kW,
Yellow phase = 18kW
Blue phase = 12kW
Line voltage = 415V
For a star connected system, we have;
The phase sequence for RYB is given by;
<em>For the Red phase;</em>
<em>For the Yellow phase;</em>
<em>For the Blue phase;</em>
For the line neutral;
Substituting we have,
D
it creates new wetland areas
Answer:
The flow velocity reduces to 0.72 m/s
Explanation:
According to the equation of continuity discharge in the channel should remain same
Thus we have
For a rectangular channel we have
Applying values in the continuity equation and since the width of the channel remains constant 3.0 m we have
The total rate of energy emission is 2786.9 W.
<h3>Total Rate of Energy Emission</h3>
Radiation is a type of heat transfer where the heat energy is conveyed from photons or electromagnetic waves. The rate of energy emission can be calculated multiplying the Stefan–Boltzmann law (σ) by area (A). Therefore, you have:
Total Rate of Energy Emission (E)= σ, where:
σ = Stefan–Boltzmann constant =
A= area
T=temperature (K)
For solving this exercise, you should apply this formula. For your question:
σ = Stefan–Boltzmann constant =
A= 0.12 m²
T=527+273=800 K
Thus, the Total Rate of Energy Emission (E) will be:
E=σ
