In a closed container, one gram of water (1 cm) is boiled under constant pressure of 1 atm (1.013 10Pa) until it changes into steam. The heat of vaporization at this pressure is Lv = 2.256 x 106J/kg = 2256 J/g. Assume that water vapor behaves like an ideal gas. The temperature of the steam is 373 K, number of moles of water vapor n = 0.0546 (g mol), the ideal gas constant R = 82.057 (cm3.atm/g mol-K). (a) How...

Question 6 Natural gas is burned in a boiler furnace. The combustion of natural gas produces 1000 kW of heat. This heat is used to convert water into saturated steam in a boiler (which is a heat exchanger). Water enters the boiler as a liquid at 20°C and leaves as saturated steam at 20 bar (absolute) a) If only 75% of the heat generated in the furnace is transferred to the boiler, calculate the steam generation rate in the boiler...

A piston-cylinder device contains water which is initially at 100 C and 20 bar. It undergoes two processes. The first process is isothermal and the second process is constant volume. The final condition is a saturated vapour at 2 bar. Calculate heat transfer and work (both in kJ/kg) for each process.
