Answer:
The line voltage of the three phase network is 346.41 V
Explanation:
Star Connected Load
Resistance, R₁ = R₂ = R₃ = 18 Ω
For a star connected load, the line current = the phase current, that is we have
Whereby the the voltage across each resistance = is given by the relation;
=
× R
Hence;
=
=
× R = 25 × 8 = 200 V
Therefore we have;
The line voltage, = √3 ×
= √3 × 200 = 346.41 V.
Hence, the line voltage of the three phase network = 346.41 V.
Answer:
Enthalpy at outlet=284.44 KJ
Explanation:
We need to Find enthalpy of outlet.
Lets take the outlet mass m and outlet enthalpy h.
So from mass conservation
m=1+1.5+2 Kg/s
m=4.5 Kg/s
Now from energy conservation
By putting the values
So h=284.44 KJ
