Answer:
The power absorbed by the 60 ohm resistor is 1.064 W
Explanation:
When there's no load connected to the source (open circuit) its voltage output is ideal, since there won't be any voltage drop across it's internal resistance. When there's a shor circuit, the only load is the internal resistance of the source, so we can use Ohm's law to compute the internal resistance, as shown bellow:
Rinternal = Vopenload/Ishortcircuit
Rinternal = 8/200 = 0.04 Ohm
When we connect a load to this source, the total load we'll be the external resistance plus the internal resistance. We can now compute the curent flow when there's a 60 Ohm resistance connected to the terminals of the source by using Ohm's law again:
I = Vsource/(Rexternal + Rinternal)
I = 8/(60 + 0.04) = 8/(60.04) = 0.1332 A
The absorbed power is the product of the voltage across the terminals of the resistor and the current that goes through it. The current is the one we calculated above and the voltage across it's terminals is given by I*R, so the power output is:
P = I*Vresistor
P = I*(I*R)
P = R*I^2 = 60*(0.1332)^2 = 1.064 W
This question is incomplete, the complete question is;
the water depths upstream and downstream of a hydraulic jump is 0.3 m and 1.2 m. Determine flow rate ( in m³ ) if the rectangular channel is 20 m wide.
Answer:
the flow rate is 32.549 m³/sec
Explanation:
Given that
y₁ = 0.3 m
y₂ = 1.2 m
β = 20 m
Now for Rectangular Channel, we know that;
2q²/g = y₁y₂( y₁ + y₂)
where g = 9.81 m/s²
and q = Q/β
so
2(Q/β)²/g = y₁y₂( y₁ + y₂)
we substitute our given values
2(Q/20)²/9.81 = 0.3 × 1.2( 0.3 + 1.2)
2(Q²/400)/9.81 = 0.36(1.5)
2(Q²/400) = 0.54 × 9.81
Q²/400 = 5.2974 / 2
Q²/400 = 2.6587
Q² = 1059.48
Q = √1059.48
Q = 32.549 m³/sec
Therefore the flow rate is 32.549 m³/sec
Answer:
USDA has developed strict measures of quality for products such as grains, rice, corn, and beans. Quality grading is based on the standards developed for each product. Quality grades provide a common language among buyers and sellers, which in turn assures consistent quality for consumers.
