Ответ:
Minimum power of compressor = 9.71 kW
Explanation:
The values of entropy, initial specific volume and enthalpy are obtained from the table for R-134a.
Entropy, s = 0.942 kJ/kg/K
Specific volume,
= 0.12355
Enthalpy,
= 241.4 kJ/kg
Final enthalpy can be found out from the table using the given pressure and entropy.
Minimum power =
=
(
)
Minimum power = 9.71 kW
