The us government reports average wind speeds across the country at a height of 100 m. a particular location in a suburban area with level ground has a reported value of 6.0 m/s, and you are asked to estimate the average wind speed at a height of 350 m. for possible installation of a drone "flying windmill for power generation. the answer is important, because power available varies as wind speed cubed. you estimate about: a. 8.5 ms b. 20 m/'s c. 6.5 m/s d. 15 m/s

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.
