Exergy is the energy that available to be used.
When system and surrounding are in equilibrium , exergy is zero
Since process 3-4 has temperature T2 .Which greater than ambient temperature To
Hence exergy will increases
Ans(b) increase
14. CO5] By inspection of the figure below, giving a Tov diagram for water, exergy will...
Steam enters a closed feed-water heater at 2 MPa and 300oC and leaves as saturated liquid at the same pressure. On the other side, cold feed-water enters the heater at 3 MPa and 35oC and leaves 10oC below the exit temperature of the steam. Neglect any heat losses from the outer surfaces of the heater and assume the surroundings to be at 25oC. Determine (a) the ratio of the mass flow rates of the extracted steam and the feedwater, (b)...
tracs.txstat.uUALUUL Questions 11-16 Consider the system for producing chilled water at the Texas State University central plant The chilled water in the cyan/blue pipes comes into contact with the chiller and delivers heat to the cold coils of the chiller. The chiller operates by receiving electrical work from the power grid. The chiller delivers heat from its hot colls to the condenser side water in the green plpes. Assume all rates are constant. Neglect any loss of mass of the...
Figure below shows a Carnot vapor power cycle. It is at steady state. Water enters the boiler as a mixture with a quality of 0.1 (point 4) and saturated water vapor leaves the boiler (point 1). Both points 2 and 3 are mixtures. Pressure in process 4-1 is 80 bar while pressure in process 2-3 is 8 bar. Turbine generates work 1-2.CV = 600 kJ/kg. (1) Plot the 4 processes: 4-1, 1-2, 2-3 and 3-4 on a P - v...

8. Below is a figure depicting the energy diagram of a reaction. Both uncatalyzed and catalyzed version of the reaction are shown. Use the figure to answer the following questions. 5 1 AAG (the reduction in AG by the catalyst) G 2 3 A+B=P+Q Reaction coordinate a. Number 4 corresponds to which of the following? a. Products (P+) b. Reactants (A+B) C. Transition state d AG of the reaction b. Which number refers to the energy diagram of the uncatalyzed...
The diagram at right shows an electric field line diagram and four labeled points. 2. (6 pts) Rank the magnitude of the electric field strength at points 1 to4 in the figure. (Remember "equal" is a possible ranking.") Indicate if the electric field strength is zero at any of the points. (8 pts) Give a good physics explanation for your ranking. This should consist of three parts. For example, if your ranking in a. is 1>2>3>4, you would first explain...
The figure below shows a thin rod, of length L and negligible mass, that can pivot about one end to rotate in a vertical circle. A heavy ball of mass m is attached to the other end. The rod is pulled aside through an angle and released. (a) What is the speed of the ball at the lowest point if L = 1.30 m, θ = 32.0°, and m = 500 kg? (b) Does the speed increase, decrease, or remain the same...

A circuit contains a battery and four identical resistors arranged as shown in the diagram above. (a) Rank the magnitude of the potential difference across each resistor from greatest to least. If any resistors have potential differences with the same magnitude, state that explicitly. Briefly explain your reasoning Ranking: Brief Explanation Resistor B is now removed from the circuit, and there is no connection between the wires that were attached to it. The new circuit diagram...
