An open tank contains water at the bottom for a depth of 6 ft and 3 ft of oil ( 0.75) above water. water is discharged from the tank through a 4-inch diameter orifice located 2 ft above the bottom. assuming steady liquid levels and no losses, determine the volume flow rate through the orifice.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

Wiy doeres rere okhn a pump whon working betwon the same pressure range?

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?
