Determine the volume change, in ft3, when 1 lb of water, initially saturated liquid, is heated to saturated vapor while pressure remains constant at 1.0, 14.7, 100, and 500, each in lbf/in.2 Comment.
For H2O, determine the specified property at the indicated state. Locate the state on a sketch of the T-y diagram.
(a) p 5 300 kPa, y 5 0.5 m3/kg. Find T, in °C.
(b) p 5 28 MPa, T 5 200°C. Find y, in m3/kg.
(c) p 5 1 MPa, T 5 405°C. Find y, in m3/kg.
(d) T 5 100°C, x 5 60%. Find y, in m3/kg.
For each case, determine the specific volume at the indicated state. Locate the state on a sketch of the T-y diagram.
(a) Water at p 5 14.7 lbf/in.2, T 5 100°F. Find y, in ft3/lb.
(b) Ammonia at T 5 230°C, x 5 50%. Find y, in m3/kg.
(c) Refrigerant 134a at p 5 1.5 MPa, T 5 100°C. Find y, in m3/kg.
