Steam at a pressure of 11 bar and a temperature of 320C is containedin a large vessel. Connected to the vessel through a valve is a turbinefollowed by a small initially evacuated tank with a volume of 0.60 m3.When emergency power is required, the valve is opened and the tankfills with steam until the pressure is 11 bar. The temperature in the tankis then 400C. The filling process takes place adiabatically and kineticand potential energy effects are negligible. Determine the amount ofwork developed by the turbine in kJ.
169 g of solid water (i.e. ice), at -17 °C, is placed into a sealed, insulated container with a volume of 0.29 m^3. A 1457 W heater is used to heat and change the phase of the sample until it is a gaseous water (i.e. steam). The heater runs for 433 s. What is the pressure, in kPa, of the gaseous water in the container at the end of the heating process? Round your answer to the first decimal place.
QUESTION 1 (a) The air inside a 0.2 m² piston-cylinder device initially at 600 kPa. After heated up for 5 minutes, the air pressure increases to 1200 kPa, while maintaining the same volume due to installation of stopper in the piston-cylinder. i. ii. iii. Calculate the boundary work experienced by this piston-cylinder device, kJ. Name the thermodynamics process. In the other case, if there is no stopper in the cylinder, the air inside the piston-cylinder device is allowed to expand to 0.35m' under isobaric condition of 600 kPa. Calculate the boundary work, kJ.
Mr Chua experimented on water movement within a rigid tank. The rigid tank isdivided into two equal parts by a partition. Initially, one side of the tank contains 5.0kg of water at 200 kPa and 25ºC, and the other side is empty. The partition is thenremoved, and the water expands into the entire tank. The water is allowed toexchange heat with its surroundings until the temperature in the tank returns to theinitial value of 25ºC. Determine:a) the volume of the tank.b) the final pressure of the tank.
A piston of mass 60 kg sits in a cylinder containing water vapour. The diameter of the piston is 20 cm. There is a spring connected above the piston which is originally unstretched, and has a spring constant of 50 kN/m. The piston moves upwards a distance of 5 cm while 200 J of heat is added. Calculate the change in internal energy of the water vapour.
20 kg of steam contained in a high-pressure tank. Tank is isolated, but heat loss to the surrounding is still occurred 1800 kJ/hr. How many kW should be added to the tank, to maintain the steam inside the tank remain constant at 3000 kPa and 600 K
