Ten kilograms of water in a piston/cylinder arrangement exist as saturated liquid/vapor at 100 kPa, with a quality of 50%. It is now heated so that the volume triples. The mass of the piston is such that a cylinder pressure of 200 kPa will float it. A. Find the final temperature and volume of the waterB. Find the work given out by the water

Water in an enclosed volume of 1 m3 has heat added until it reaches a temperature of 150 Celsius. If there is 4 kg of water in the container, find the final pressure in kPa of the water, its final mass of the water vapor in kg and the final volume of the water vapor.

A cylinder fitted with a piston has a volume of 0.1 m'and contains a 0.8 kg of steam at 0,.4 MPa. Heat is trausferred to the steam umntil the temperature is 250°C, while the pressure remmains constant. (1) vi (specific volume) in m'kg = (2) v: (specific volume) in m'kg = (3) xi (quality) = .

A 12hp motor is used to drive an air compressor. The compressor efficiency is 70%. Find the mass of air in kg needed per minute if air is available at 30C. The pressure compresses to 8 times its original pressure. Ans: 1.52

2. 0.3 kg of carbon dioxide is contained in the cylinder with the piston. Initial conditions are 200 kPa, 30 °C. It was compressed to 600 kPa by an isothermal process (a process where the temperature is constant). Find out what has been done during this process.

Q3: You have an ideal gas in an insulated container. You compress it from a pressure of 40 × 105 Pa to 20 × 105 Pa, while increasing the volume from 10 to 20 m3. What is the work you done by the gas a- 10 J b- 300 J c- 500 J d- 880 J

A piston cylinder provides an 800 kPa on steam which has a quality of 0.95 and an volume of 1200 cm^3. What is heat transfer need to raise the temperature to 400 C

Ammonia (an ideal gas) is contained in a 1.5 cubic meter piston. Initially, it is 200 kPa, 20C but it is compressed to 40C (at constant pressure). During this process, 1500 kJ of heat is rejected to the 20C surrounding and 750 kJ of work is done. Is this process possible?
