9 A velocity field is specified as V ! =axy^i+by2^j, where a= 2 m−1s−1, b= −6 m−1s−1, and the coordinates are measured in meters. Is the flow field one-, two-, or three-dimensional? Why? Calculate the velocity components at the point ð2, 1 2Þ. Develop an equation for the streamline passing through this point. Plot several streamlines in the first quadrant including the one that passes through the point ð2, 1 2Þ.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
