Question

In a chemical industry, throttling valves are commonly used to reduce the pressure in the pipe lines. Refrigerant-134a is throttled from the saturated liquid state at 700 kPa to a pressure of 160 kPa.

(a)          State assumption made for this process.                                                             

(b)          Calculate the temperature drops during this pressure (°C).                                     

(c)          Determine the final quality of refrigerant, if any.   

(d)          Determine the final specific volume of the refrigerant (m³/kg).
