A tank that initially contains H2O at 0.05 MPa and 100 ºC, is connected to a water vapor line at 0.60 MPa and 200 ºC and is filled to a level where 90% (on a volumetric basis) is liquid. The 1 m3 tank is kept at 100 ºC during the process. Determine the quality of the gas in the second phase, the input mass in (kg) and the heat transfer, in kJ.

A 2-m3 rigid insulated tank initially containing
saturated water vapor at 1 MPa is connected through a valve to a
supply line that carries steam at 400°C. Now the valve is opened,
and steam is allowed to flow slowly into the tank until the
pressure in the tank rises to 2 MPa. At this instant the tank
temperature is measured to be 300°C. Determine the mass of the
steam that has entered and the pressure of the steam in the...

A
200 litre tank initially contains water at 100 kPa and a quality of
1%. Heat is transferred to the water, thereby raising its pressure
and temperature. At a pressure of 2 MPa, a safety valve opens, and
saturated vapour at 2 MPa flows out. The process continues,
maintaining 2 MPa inside until the quality in the tank is 90%, then
stops. Determine the total mass if water that flowed out and the
total heat transfer.

A 100 gallon tank initially contains 10 gallons of fresh water.
At t=0 a brine solution containing 1 pound of salt per gallon is
poured into the tank at the rate of 4 gal/min., while the
well-stirred mixture leaves the tank at the rate of 2 gal/min. Find
the amount of salt in the tank at the moment of overflow.
Enter answer as numerical decimal correct to two decimal places.

A steel tank contains water at ? = 1.00 MPa and ℎ = 3100 kJ/kg.
Determine the following:
a. State of the water; ie whether the water is compressed water
or saturated water or superheated vapour? (Hint: Use Saturated
water—Pressure table to compare ℎ at ? = 1.00 MPa)
b. Estimate the temperature of the water. (Hint: Use Saturated
water—Pressure table or Superheated water, depending on the state
you find in a)

A
tank contains 100 gal of water. Brine enters the tank at the rate
of 3 gal/min. The mixture, thoroughly stirred, leaves the tank at
the rate of 2 gal/min. If the salt concentration in the brine at
the end of 20 minutes is to be 2 lb/gal, what should be the salt
concentration in the brine entering the tank?

A rigid tank contains hydrogen and has a volume of 4.1
ft3. It is initially at 87°F and 1,072 psia. Hydrogen
then leaks from the tank until it is 76°F and 158 psia. How much
heat transfer occurred into the tank, in Btu. Answer negative if
heat left the tank.

A tank initially contains 10 liters of clean water (with no salt
in it). Every minute, a solution containing one liter of water and
one gram of salt is added to the tank, and two liters of fluid are
drained from the tank. The fluid in the tank is mixed continuously
so that the salt is distributed evenly throughout the water in the
tank. How many minutes does it take for the tank to contain 2 grams
of salt?
