Hydraulic jump occurs in a rectangular channel with the flow rate of 500 ft3/s and width of 10 ft. If the depth of flow before the jump is 3.1 ft, what would be the depth after the jump, head loss during the jump, and velocity after and before the jump

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?
