Answer:
90 L.atm
Explanation:
According to the provided details:
First pathway:
A( 3 atm, 20 L) → C ( 1 atm, 20 L) → D (1 atm, 50 L)
Second pathway:
A(3 atm, 20 L) → B( 3 atm, 50 L) → D ( 1 atm, 50 L)
As the number of moles is 1.00 moles
To calculate wAB;
A → B signifies the transformation is happening at a steady pressure;
Thus,
wAB = pressure multiplied by the change in volume
wAB = P(V₂ - V₁)
wAB = 3 atm (50 L - 20 L)
wAB = 3 atm (30 L)
wAB = 90 L.atm
That statement is incorrect!
The claim is untrue
Answer:
The change in entropy of the steam is 2.673 kJ/K
Explanation:
The mass of the liquid-vapor mixture is 1.5 kg
The mass in the liquid phase is calculated as 3/4 × 1.5 kg = 1.125 kg
The mass in the vapor phase is calculated as 1.5 - 1.125 = 0.375 kg
According to the steam tables
At a pressure of 200 kPa (200/100 = 2 bar), the specific entropy of steam is found to be 7.127 kJ/kgK
The entropy of steam can be calculated as specific entropy multiplied by mass = 7.127 × 0.375 = 2.673 kJ/K
Answer:
An attachment follows below
Explanation:
1) The formula used for the damping coefficient in a series RLC circuit.
If \xi = 0, it is possible to set c = 0 but an inductor will still possess some capacitance.
2) The behaviors of critically damped and underdamped systems are illustrated along with comments on their temporal responses.
4) While several answers might suffice, the four I’ve highlighted are the crucial parameters necessary about an unknown op-amp before utilizing it in a circuit.
Hope this addresses all your inquiries.
Answer:
B) P1 would have to increase to sustain the flow rate (correct)
C) Resistance would rise (correct)
Explanation:
Flow rate is measured at 10 liters per minute
Driving pressure (P1) stands at 20 cm H2O
Fixed downstream pressure (P2) is 5 cm H2O
The accurate statements when the lumen is pinched in the center of the tube are: P1 will increase to maintain the flow rate, and resistance will rise. This occurs because pinching the lumen decreases its diameter, leading to higher resistance, which is linearly related to pressure, thus P1 will also increase.
The incorrect statement is: the flow would decrease.
