1. ammonia at 20 c with a quality of 50% and a total mass of 2 kg is in a rigid tank with an outlet valve at the bottom. how much liquid mass can be removed through the valve assuming that the temperature stays constant?
and from so table in the text
saturated press.= 857.5kps (@20 c)
saturated specific volume Vf = 0.001638 [m^3/kg]
saturated specific volume Vg = 0.1422 [m^3/kg]
mass liquid =1 kg
mass gas= 1kg
Vf * 1kg = 0.001638 m^3
Vg* 1kg= 0.1422 m^3
v of tank = 0.150858 m^3
(0.001638 m^3)/(Vg = 0.1422 [m^3/kg])= 0.0109770808kg
1kg (of liquid) -0.0109770808kg ( mass of gas needed to fill the liquids space) = .9890229192 kg of liquid can be removed from the tankcan anyone tell me if that's right?
