Chapter 6, Problem 6.14P

Step by step solution please I only have 1 attempt thank you.

solve the following problem: Steam enters a turbine operating at steady state at 850oF and 450 lbf/in2 and leaves as a saturated vapor at 1.4 lbf/in2. The turbine develops 12,000 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 2 x 106 Btu/h. Neglect kinetic and potential energy changes from inlet to exit. Determine the exit temperature, in oF, and the volumetric flow rate of the steam at the inlet, in ft3/s.

Steam enters a turbine operating at steady state at 850oF and 450 lbf/in2 and leaves as a saturated vapor at 1.2 lbf/in2. The turbine develops 12,000 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 2 x 106 Btu/h. Neglect kinetic and potential energy changes from inlet to exit. Determine the exit temperature, in oF, and the volumetric flow rate of the steam at the inlet, in ft3/s.

Two pounds mass of water in a piston-cylinder assembly, initially a saturated liquid at 45 lbf/in2, undergoes a constant pressure, internally reversible expansion to x2 = 90%.For this reversible process, determine the work by integrating p dV and the heat transfer by integrating T dS, each in Btu.

#1. A closed, rigid tank fitted with a fine-wire electric resistor is filled with Refrigerant 22, initially at -14 °C, a quality of 70%, and a volume of 0.01 m³. A 12-volt battery provides a 5-amp current to the resistor for 5 minutes. If the final temperature of the refrigerant is 40 °C, determine the heat transfer, in kJ, from the refrigerant to the surrounding environment. Refrigerant 22 T = -14°C x1 = 70% T2 = 40°C V = 0.01 m³ Resistor 12-volt battery provides a 5-amp current for 5 minutes. l000000000000000

One kilogram of ammonia initially at 8.0 bar and 50oC undergoes a process to 3.7 bar, 20oC while being rapidly expanded in a piston–cylinder assembly. Heat transfer between the ammonia and its surroundings occurs at an average temperature of 40oC. The work done by the ammonia is 40 kJ.  Kinetic and potential energy effects can be ignored.  Determine the heat transfer, in kJ, and the entropy production, in kJ/K.

One kg of an ideal gas (gas constant R = 287 J/kg.K) undergoes an irreversible process from state-1 (1 bar, 300 K) to state -2 (2 bar, 300 K). The change in specific entropy (52 - s1) of the gas (in J/kg. K) in the process is

For state 1, how did you determine the value for hg = 2509.33 kJ/kg?

Three pounds mass of water in a piston–cylinder assembly, initially a saturated liquid at 45 lbf/in2, undergoes a constant pressure, internally reversible expansion to x2 = 90%.For this reversible process, determine the work by integrating p dV and the heat transfer by integrating T dS, each in Btu.
