Five lbs of propane is contained in a closed, rigid tank
initially at 80 lbf/in.2, 50°F. Heat transfer occurs
until the final temperature in the tank is 0°F. Kinetic and
potential energy effects are negligible.
Determine the amount of energy transfer by heat, in Btu.

A closed, rigid tank contains water initially at 250 °F with a
quality of 0.4. The tank is heated until the water reaches 290 °F.
Find the initial and final pressure, in lbf/in2 . Sketch the
process on P-υ and T-υ diagrams (be sure to include the vapor dome,
constant temperature and pressure lines, number your states, and
indicate the process direction with an arrow). Thermodynamic

Five kg of oxygen (O2), initially at 430°C, fills a closed,
rigid tank. Heat transfer from the oxygen occurs at the rate 425 W
for 10 minutes. Assuming the ideal gas model with k
= 1.350 for the oxygen, determine its final temperature, in
°C.
Can't seem to find the right equations to use for this one, so
I'm getting pretty stumped. Any help would be greatly
appreciated

A propane tank with 75 gallons of liquid propane is at 50 F in a
sealed tank. The tank develops a significant leak and propane
escapes and vaporizes in a short period of time. To solve this
problem you must use the propane tables not the common liquid
properties.
What is the temperature near the hole in the propane tank
due to the escaping propane in Fahrenheit to three significant
digits? . Include a minus sign if
appropriate.

A closed, rigid tank is filled with water. Initially, the tank
holds 0.6 lb of saturated vapor and 6.0 lb of saturated liquid,
each at 212°F. The water is heated until the tank contains only
saturated vapor. Kinetic and potential energy effects can be
ignored.
Determine the volume of the tank, in ft3, the temperature at
the final state, in °F, and the heat transfer, in Btu.

A closed rigid tank contains 2 kg of water at 80 C and
quality of 0.5815. The tank is then heated until it contains
only
saturated vapor. How much heat (in kJ) is added to reach this
condition? Include a drawing and plot the process on a P-V
diagram.

Water is contained in a closed, rigid, 0.2 m3 tank at
an initial pressure of 5 bar and a quality of 50%. Heat transfer
occurs until the tank contains only saturated vapor. Determine
a)the final mass of vapor in the tank, in kg,b)
the final pressure, in bar.

Problem 3.034
A closed, rigid tank is filled with water. Initially, the tank
holds 0.4 lb of saturated vapor and 4.0 lb of saturated liquid,
each at 212°F. The water is heated until the tank contains only
saturated vapor. Kinetic and potential energy effects can be
ignored.
Determine the volume of the tank, in ft3, the
temperature at the final state, in °F, and the heat transfer, in
Btu.

A mass of m=1kg of steam is contained in a closed rigid
container. Initially the pressure and temperature of the steam are:
p1= 1.5 MPa and t1=240?C, respectively. Then the temperature drops
to T2 =100?C as the result of heat transfer to the surroundings.
Determine: a) quality of the steam at the end of the process, b)
percentage of volume that is occupied by the saturated liquid at
the final state, c) heat transfer with the surroundings per unit
mass...
