gas expands from an initial volume of 0.2 m to a final volume of steady flow process. During the process, the pressure varies with the volume as A P = 5 x 10 V + 7 x 104 where P is in N/m² and V is in m. The inlet line is 4 m below the outlet line and the gas enters with a negligible velocity. The internal energy of the gas decreases by 30 kJ during the process. Determine the heat transferred.

The answer should be around 580,000J

2.14 A gas expands from an initial volume of 0.2 m³ to a final volume of 0.4 m³ in a reversible steady flow process. During the process, the pressure varies with the volume as P = 5 × 10° V + 7 × 10ª where P is in N/m² and V is in m³. The inlet line is 4 m below the outlet line and the gas enters with a negligible velocity. The internal energy of the gas decreases by 30 kJ during the process. Determine the heat transferred.
