Consider a box with two chambers labeled 1 and 2. Each chamber is filled with identical ideal gases that are initally at the same pressure, temperature, and volume; and the vertical wall between the chambers is free to move without transferring any thermal energy or gas between the chambers. Each chamber starts at an initial volume of 2 m and pressure 100 kPa. We then heat the gas of Chamber 1, which causes the dividing wall to move. When the...

Consider a box with two chambers labeled 1 and 2. Each chamber is filled with identical ideal gases that are initially at the same pressure, temperature, and volume; and the vertical wall between the chambers is free to move without transferring any thermal energy or gas between the chambers. Each chamber starts at an initial volume of 2 m^3 and pressure 100 kPa. We then heat the gas of Chamber 1, which causes the dividing wall to move. When the...

4. A rigid tank with a volume of 2 m has two chambers, each of 1 m in volume, containing gas 1, with v1-0.8 m3/kg and gas 2 with V2 = 1.2 m3/kg. a. If the two gases are allowed to mix, what is the new specific volume? b. After they mix, a piston compresses the gases until the volume of the tank is 0.5 m What is the final specific volume of the mixed gas after this compression process?...

1)Two rigid tanks of equal size and shape are filled with different gases. The tank on the left contains oxygen, and the tank on the right contains hydrogen. Assume both gases are ideal. The molar masses of oxygen and hydrogen are 32 and 2, respectively. Both containers are at the same temperature. A pressure gauge is pin oxygen hydrogen connected to each tank. Both gauges show a reading of 230 kPa. Is the number of oxygen molecules in the left...

2. Consider a combined gas steam power cycle. The gas cycle is a
simple Brayton cycle that has a pressure ratio of 7. Air enters at
9.8 kg / s at the compressor at 15 ° C and 100 kPa, and at the gas
turbine at 950 ° C. The steam cycle is a Rankine cycle with
overheating between the pressure limits of 6 MPa and 10 kPa. The
water vapor is heated in the heat exchanger at a rate...

Consider the piston/cylinder arrangement shown in Fig1. A
frictionless piston is free to move between two sets of stops. When
3 the piston rests on the lower stops, the enclosed volume is 0.5
m3. When the piston reaches the upper stops, the volume is 0.8 m .
The cylinder initially contains water at 200 kPa, 60% quality. The
mass of the piston requires 600 kPa pressure to move it against the
outside ambient pressure.
a) When heat is transferred until...

Problem 1 0/5 points (0%) Consider a combined gas-steam power plant that has a net power output of 500 MW. The pressure ratio of the gas-turbine cycle is 12. Air enters the compressor at 308 K and the turbine at 1300 K. The combustion gases leaving the gas turbine are used to heat the steam at 9 MPa to 360°C in a heat exchanger. The combustion gases leave the heat exchanger at 460 K. An open feedwater heater incorporated with...
