4.40 A rigid, insulated tank consists of two compartments of equal volume separated by a valve. Initially, one compartment contains air at a pressure of 750 kPa and a temperature of 50°C, while the second compartment is completely empty. The valve is opened and it remains open until the two compartments reach pressure and temperature equilibrium. Determine the final pressure and temperature of the air, assuming each compartment has a volume of 0.65 m'.

A system is given by two compartments separated by a thin
membrane, and solute moves from one compartment to the other by
diffusion. The volume of compartment 1 is 0.03 cm^3 and compartment
2 is 0.01 cm^3. Suppose 50 M of solute is dumped into compartment
2, and the concentration response for compartment 1 is c1(t)=
1250(1- e^(-0.01t) u(t) M/cm^3 . (a) Find the transfer
rate. (b) Solve for the concentration in compartment 2.

Ilustrated is a completely isolated system comprised of two compartments A & B) containing two monovalent molecular species (1 & 2). The compartments are separated by an ultrathin, freely moving and thermally conducting membrane that is permeable to only species 1. NA and N denote the number of molecules of species 1 occupying, respecively, compartments A and B at time t and NA and NB denote the number of molecules of species 2 occupying, respectively, compartments Freely moving membrane permeable...
An insulated tank has two compartments connected by a membrane. Initially, one compartment contains 0.4 kmol of CO2 at 150 ̊C, 600kPa and the other contains 0.3 kmol of N2 at 100 ̊C, 300kPa. The valve...
An insulated tank has two compartments connected by a membrane. Initially, one compartment contains 0.4 kmol of CO2 at 150 ̊C, 600kPa and the other contains 0.3 kmol of N2 at 100 ̊C, 300kPa. The valve is opened and the gases are allowed to mix until equilibrium is achieved. Determine the final temperature, pressure, and the amount of entropy generation.

Problem 3-2 A rigid, well-insulated tank consists of two compartments eparated by a valve, one being twice the volume of the other. Initially, the smaller compartment contains 10 kg of nitrogen at 6 bar and 100°C, while the larger one is evacuated. The valve is opened and the gas expands to fill the total volume, eventually achieving an equilibrium state. Calculate: a) The final temperature, in K. b) The final pressure, in bar, c) The total exergy destroyed, in kJ...

Two solutions are separated by a semipermeable membrane. The volume of compartment A increases while the volume of compartment B decreases. This information suggests which TWO of the following are true? (choose TWO) Select one or more: Compartment A was initially isotonic to compartment B. Compartment A initially had a higher osmolarity than compartment B. Compartment A initially had a lower osmolarity than compartment B. Compartment A was initially hypotonic to compartment B. Compartment A was initially hypertonic to compartment...

Consider a well-insulated horizontal rigid cylinder that is divided into two compartments by a piston that is free to move but does not allow either gas to leak into the other side. Initially, one side of the piston contains 1 m3 of N2 gas at 500 kPa and 120 °C, while the other side contains 1 m3 of He gas at 500 kPa and 40 °C. Now thermal equilibrium is established in the cylinder as a result of heat transfer...
An isolated chamber with rigid walls is divided into two equal compartments
An isolated chamber with rigid walls is divided into two equal compartments, one containing steam at 10 bar and 370oC, and the other evacuated. A valve between the compartments is opened to permit steam to pass from one chamber to the other. a)After the pressure (but not the temperatures) in the two chambers have equalized, the valve is closed, isolating the two systems. What are the temperature and pressure in each cylinder?b)If the valve were left open, and equilibrium state...

An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...
