Question

Two insulated containers are connected through an insulated line
and a valve that is closed. Both sides contain 1 kg of steam but
the left side is at 300 °C while the right side is at 200 °C. The
valve is opened, allowing both sides to mix and reach a common
temperature and pressure.

a) Is this process reversible?

b) What is the final pressure and temperature of the steam, if the
steam is treated as an ideal gas?

c) Comment on whether it is reasonable to treat steam as an ideal
gas under these conditions.

Answer #1

A rigid, insulated tank that is initially evacuated is connected
through a valve to a supply line that carries steam at 1 MPa and
300°C. Now the valve is opened,and steam is allowed to flow slowly
into the tank until the pressure reaches 1 MPa, at which point the
valve is closed. Find the rate of entropy production.

Two thermally insulated vessels are connected by a narrow tube
fitted with a valve that is initially closed as shown in the figure
below. One vessel of volume V1 = 17.1 L, contains oxygen at a
temperature of T1 = 310 K and a pressure of P1 = 1.80 atm. The
other vessel of volume V2 = 23.0 L contains oxygen at a temperature
of T2 = 470 K and a pressure of P2 = 1.80 atm. When the valve...

wo insulated cylinders A and B with
volumes
VA = 2.0
m3
and
VB = 6.8
m3
contain chlorine gas at different pressures and temperatures.
The cylinders are insulated (no heat is lost to or gained from the
outside) and connected by a valve. Initially, the valve is closed
and the gas in the two cylinders has the following values:
PA =
4.0 105 N/m2,
TA = 220 K,
PB =
2.5 105 N/m2,
TB = 580 K.
The valve is opened...

A rigid, insulated vessel is divided into two compartments
connected by a valve. Initially, one compartment, occupying 1.0
ft3, contains air at 50 lbf/in2,
500oR, and the other, occupying 2.0 ft3, is
evacuated. The valve is opened and the air is allowed to fill both
volumes. Assume the air behaves as an ideal gas and that the final
state is in equilibrium.
Determine the final temperature of the air, in oR, and
the amount of entropy produced, in Btu/oR.

A rigid, well-insulated tank contains 100 kg of liquid water at
21°C. The tank is connected through a valve to a steam main where
the pressure is 1 MPa. The valve is opened and steam enters the
tank until the water temperatuere rises to 65 °C, at which time the
valve is closed. It is determined that there are now 107.96 kg of
water in the tank. Estimate the quality of steam in the main.

Three thermally insulated containers of equal volume are
connected together by thin tubes of negligible volume so that gas
can flow from one container to the next when a valve between them
is open. Initially, the pressure and temperature in each container
is at the same value Po and To,
respectively.
The valves between the vessels are opened, and thermal insulation
is removed from two of the vessels. Then two vessels are surrounded
by heat reservoirs so that their temperatures...

Consider two containers,
Both have volume 0.1 m3, and pressure 106
Pa
One contains monatomic ( 3 degrees of freedom) He at T= 124 K
and
One contains diatomic (5 degrees of freedom) N2 at T
= 238 K.
A valve is opened allowing these two gases to mix. They are kept
thermally isolated from the outside.
You can treat them as ideal gases.
1)
What is the change in internal energy under this process?
2)
What is the final...

Two identical sealed containers (1 and 2) are connected to one
another by a narrow tube with a valve. Initially, the valve is
closed, container 1 is filled with a fluid, and container 2 is
empty. Both containers have a ruler taped to their sides in order
to measure the height of any fluid they contain.
A) . When the valve is opened for a time interval Δt, the level
of the fluid in container 1 drops by 3 cm....
