- A cylinder fitted with a piston has a volume 0.1 m3 and contains 0.5 kg of steam at 500 kPa. How much heat is to be supplied to bring the temperature of the steam to 823 K keeping the pressure constant? What is the work done in the process? Answer: Q = 914.86 kJ, W = 139.35 kJA frictionless piston–cylinder device contains 16 lbm of superheated water vapor at 40 psia and 600°F. Steam is now cooled at constant pressure until 70 percent of it, by mass, condenses. Determine the work done during this process.The radiator of a steam heating system has a volume of 20 L and is filled with superheated water vapor at 200 kPa and 200°C. At this moment both the inlet and the exit valves to the radiator are closed. After a while it is observed that the temperature of the steam drops to 80°C as a result of heat transfer to the room air, which is at 21°C. Assuming the surroundings to be at 0°C, determine the maximum amount of heat that can be supplied to the room if this heat from the radiator is supplied to a heat engine that is driving a heat pump. Assume the heat engine operates between the radiator and the surroundings.
- A student living in a 4 - m 5 - m 3 - m dormitory room turns on her 100 - W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the windows are tightly closed and disregarding any heat transfer through the walls and the windows, determine the temperature in the room when she comes back 8 h later. Use specific heat values at room temperature, and assume the room to be at 100 kPa and 20 ° C in the morning when she leaves.An inventor claims to have devised a process using only saturated steam at 100C which by a complicated series of steps, make heat continuously available at T of 177C. He claims further that, for every kilogram of steam taken into the process, 1800 kJ of energy as heat is liberated at this higher T of 177C. Show whether or not such a process is possible. In order to give the inventor the benefit of any doubt, assume cooling water to be available in unlimited quantity at 0C. topic: introduction to chemical engineerint thermodynamicsIs the energy required to heat air from 295 to 305 K the same as the energy required to heat it from 655 to 675 K?
