6) A gear train (shown below) is composed of four gears, A, B, C, and D. Gear A has 16 teeth and is meshed with gear B. Gear B has 32 teeth and shares a shaft
with gear C, which has 14 teeth. Gear C is meshed with gear D, the output gear
which has 42 teeth. What is the gear ratio of the train? *

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
