A device( piston) has 20,000g of Water initially has a volume of 0.65 m³ at 255°C. The piston device is then connected to a heat exchanger, which allows the heat transfer to the water at a rate of 33.71 kW until a final state of 400°C while the pressure remains constant as initial pressure. Inside the piston device, a shaft work of 13.86 kW is continuously provided to improve mixing of water. an inlet stream of water at 1300°C and 1 MPa may be introduced at a mass flow rate of 4.3 kg/s through the valve if the valve is allowed to be open. Piston Water Inlet stream Wsh Piston-cylinder device (a) Determine the initial phase and properties (pressure, internal energy, and enthalpy) of the the water inside the piston-cylinder. b) Determine the final phase and properties (internal energy and enthalpy) of the water inside the piston-cylinder. (c) Determine the phase and properties (internal energy and enthalpy) of the water in the inlet stream. (d) Determine the duration of heat transfer process if the valve is fully closed. (e) Determine the duration of heat transfer process if the valve is fully opened. A device( piston) has 20,000g of Water initially has a volume of 0.65 m³ at 255°C.
