5. A fluid undergoes a reversible adiabatic compression from 0.5 MPa, 0.2m to 0.05 m according to the law, pV1= c. Calculate the change in enthalpy, entropy and internal energy. Also, compute the heat transfer and work nonflow during the nrocess

A tank is perfectly insulated and divided into two parts by amembrane. The first part occupies 5 m3 volume containing air at 100 kPapressure and 300 K temperature and the second one 2 m3air at 2 MPa and 300k. The membrane suddenly raptures somehow, and then thermodynamicequilibrium is established. (a) Find the final temperature, pressure and entropy change of air, (b) Calculate the entropy generation during this process.

Quick please

Moist air, saturated at 2°C, enters a heating coil at a rate of 10 m3/s. Air leaves the coil at 40°C. Find the required rate of heat addition. I NEED COMPLETE SOLUTION, PLEASE DONT USE PSYCHOMETRIC CHART. USE IT AS A CHECKING.

2.Ammonia gas(k=1.32) flows isentropically from100kPa and 130C to 400kPa with required input compressor work of 360 kW. Find the mass flow rate of ammonia gas.

Two insulated Tanks are connected with an insulated  pipe and a valve. The valve is open and steam flows from Tank A to tank B in a quasi static proccess until the valve is closed. The  specific entropy in each tank is maintained the same, but the total entropy in the system is changed , explain why .

R-134a in saturated liquid form at -16 degree in an ice machine is evaporated to atmosphericpressure and ensured to freeze at 0 degree. R-134a is leaving from the evaporator as saturated vaporis known. The device produces ice at a flow rate of 2000 kg / h and a temperature of 0 degree. Calculate the entropy generation rate.

saturated steam at 0.6 mpa is compressed in an irreversible adiabatic process with an effieciency of 80% for a final pressure of 0.46 mpa. find final and initial entropies
