Nitrogen at 500 KPa, 500K is in a 1m3 insulated tank connected to a pipe with a value to a second
insulated initially empty tank of 0.5m3. The value is opened and the nitrogen fills both tanks. Find the
final temperature, pressure and the entropy generation this process causes.(the gas constant of nitrogen is R=0.2968 KJ/Kg?K)

An insulated tank containing 0.5m3 of R-134 at 500 kPa and 90%
quality is connected to an initially evacuated insulated
piston-cylinder device. The force balance on the piston is such
that a pressure of 120kPa is required to lift the piston. The valve
is then opened slightly and part of the refrigerant flows to the
cylinder, pushing the piston up and the final cylinder volume is
1.5 m 3 . The process ends when the pressure in the tank drops...

An insulated, rigid tank whose volume is 0.5 m3 is
connected by a valve to a large vessel holding steam at 40 bar,
480°C. The tank is initially evacuated. The valve is opened only as
long as required to fill the tank with steam to a pressure of 20
bar.
Determine:
(a) the final temperature of the steam in the tank, in °C, the
final mass of the steam in the tank, in kg, and
(b) the amount of entropy...

Nitrogen undergoes an isothermal process from 100 kPa to 500
kPa, T = 300K. How much specific work was required for this
process?

A 1.0 m3 tank, initially filled with 103. kPa, 300. K
air, is connected to a source of air at 1,500. kPa, 300. K. The
tank slowly fills until it is at the same pressure. If the
temperature is maintained at 300. K throughout this transient
process, what is the total heat transfer required? (You can assume
air is an ideal gas.)

An adiabatic tank, 0.5 m3, is initially evacuated and charged
with steam at 500 kPa and 300 C. The final tank pressure is 500
kPa. Determine the final temperature and the entropy
production.

A
rigid tank contains air at 500 kPa and 190 °C. As a result of heat
transfer to the surroundings, the temperature and pressure inside
the tank drop to 64 °C and 400 kPa respectively. One kilogram of
water fills a container whose volume is 0.13 m cube. The pressure
in the container is 750 kPa. Calculate the total internal energy
and enthalphy in the container.

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 gasoline storage tank drains by gravity to a tank truck; see
the drawing. The pipe line between the tank and the truck is 100 m
of 0.1 m diameter commercial steel pipe. The properties of gasoline
are given as, density=720 kg/m3, dynamic viscosity = 0.0006 kg/m.s.
Both tank and truck are open to the atmosphere, and the level in
the tank is 10 m above the level in the truck. What is the
volumetric flow rate of the gasoline?...
