A system consisting of 1 kg of water undergoes a cycle composed of the following processes:

Process 1-2: constant-volume heating from p1 = 500 kPa, T1 = 160°C to p2 = 1000 kPa.

Process 2-3: constant-pressure process to saturated vapor.

Process 3-4: constant-volume cooling.

Process 4-1: isothermal expansion with Q41 = 815.8 kJ.

 

Neglecting kinetic and potential energies, determine the work and heat transfer for each process, all in kJ.

What is the local heat transfer coefficient : A flat plate maintained at a temperature of 50 C experiences a flow of atmospheric air at 15 C. If the temperature gradient at the plate's surface at a given downstream location is -43 C/mm, what is the local heat transfer coefficient?
Water flows across flat plate at a velocity : Water at 20 C flows across a flat plate at a velocity of 0.25 m/s. compute the distance from the plate’s leading edge to where the laminar boundary layer thickness is 3 cm. Verfiy that the flow is indeed lamiar at this distance.
Water in thermal equilibrium-trailing edge of the plate : Water in thermal equilibrium with a 50 C plate flows across the plate at a velocity of 0.5 m/s. find the length of the plate required such that the critical Reynolds number is achieved at the trailing edge of the plate.
Determines work done and heat transfer : For the cylinder-piston shown, piston is initially resting on the lower stops. The cylinder contains 1 kg of water at 1 bar and x = 0.64. A pressure of 3 bars is required to move the piston. The system is now heated until the water reaches 600° C.
Water undergoes a cycle composed : A system consisting of 1 kg of water undergoes a cycle composed of the following processes: constant-volume heating from p1 = 500 kPa, T1 = 160°C to p2 = 1000 kPa. constant-pressure process to saturated vapor.
Work for first process and heat transfer for second process : Air is compressed adiabatically from p1 = 100 kPa, T1 = 300 K to p2 = 1500 kPa, v2 = 0.1227 m3 /kg.

Determine the final equilibrium pressure : An ideal gas is confined to one side of a rigid, insulated container divided into equal volumes by a partition. The other side is initially evacuated. The following data are known for initial state of the gas: p1 = 300 kPa, T1 = 380K and V1 = 0.025 m..
Specimen of this material elongate when a true stress : For some metal alloy, a true stress of 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 417 MPa (60480 psi) is applied if the original length is 470 mm (18.50 in.)? A..
Stress necessary to plastically elongate a specimen : A cylindrical specimen of a metal alloy 48.0 mm long and 9.72 mm in diameter is stressed in tension. A true stress of 368 MPa causes the specimen to plastically elongate to a length of 53.5 mm.
