(3) Water 5m (1) (2)

Consider the the inclined wall shown in Figure . The wall is 0.89 mm wide. ρwρw = 1000 kg/m3. Determine the x and y components of the resultant force the water exerts on side AB and CD of the wall.

Need help with this engineering problem. The answer needs to be in meters.

A vertical cylinder with crosssectional area A = 1 dm2  contains h1 = 25 cm of water at the bottom. The space above it is filled with the saturated vapour of the water, which is separated from the external space by a piston. The bottom of the piston is h2 = 75 cm above the water level. The density of water at this temperature is n = 2 times the density of saturated vapour. (a) If temperature is held constant, by how much should the piston be pushed down in order to decrease the volume of vapour to V = 4.5 dm3 ? (b) If temperature is held constant, by how much should the piston be pushed down in order to have the vapour condense completely?
