C. Positive or negative depending on the zone
Answer:
Expression for output voltage = V = Vo sin wt
Explanation:
Amplitude of output voltage = Vo = 19 V
Frequency = f = 240 Hz
Now we know that
Angular frequency = w = 2 π (1 / T) = 2 π 240 = 480 π Hz
Expression for output voltage = V = Vo sin wt
Expression for output voltage = V = 19 (sin 480 π) t
A) The pressure (p)=400kPa=0.400MPa
Mass of mixture =M
quality (X)= 0.60
Volume of mixture (V)=10 m3
From steam table at P=0.400MPa
Specific volume of saturated water (vf)=0.00108355 m3/kg
Specific volume of saturated steam (vg)=0.46238 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.00108355+0.6(0.46238-0.00108355)]
M=36.04748 kg
If pressure is lowered to 300kPa
p=0.300MPa
From steam table we get,
Specific volume of saturated water (vf)=0.00107317 m3/kg
Specific volume of saturated steam (vg)=0.60576 m3/kg
Therefore, the volume of steam having X=0.6 is given by
V=M[vf+X(vg-vf)]
10= M[0.001007317+0.6(0.60576-0.00107317)]
M= 26.4825 kg
