1. For each case, determine the specified property data and locate the state by hand on a sketch of the T-y diagram.

(a) Evaluate the specific volume, in ft3/lb, and the specific enthalpy, in Btu/lb, of water at 400°F and a pressure of 3000 lbf/in.2

(b) Evaluate the specific volume, in ft3/lb, and the specific enthalpy, in Btu/lb, of Refrigerant 134a at 95°F and 150 lbf/in.2

(c) Evaluate the specific volume, in m3/kg, and the specific enthalpy, in kJ/kg, of ammonia at 20°C and 1.0 MPa.

(d) Evaluate the specific volume, in m3/kg, and the specific enthalpy, in kJ/kg, of propane at 800 kPa and 0°C.

2. Water, initially saturated vapor at 4 bar, fills a closed, rigid container. The water is heated until its temperature is 400°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored.
