An air pump is used to fill a rigid gas bottle with air. The pump is connected to the gas bottle via a rigid pipe. The pump consists of a piston of internal diameter d=0.08 m and a cylinder with a stroke L=0.3m. Air enters the pump through an orifice located at the bottom of the cylinder to raise the pressure in the pump to atmospheric pressure. Air, drawn into the pump through the orifice, mixes completely and adiabatically with the cylinder contents. A valve allows the bottle's refill. The valve opens when the pump pressure is equal to the gas bottle. The valve is always closed when the pump pressure is below the gas bottle pressure. Pressure drop across the valve can be neglected. The bottle, the connecting pipe and the pump are thermally insulated. Air in the pump and connecting pipe undergoes isentropic compression and expansion processes. I F-one The working fluid (air) can be considered a perfect gas with R=287 J/KgK, cp=1005 J/KgK and y=1.4. Initially the piston is located at…
thermodynamics Sketch the diagram for the system and show pertinent solutions. (show cancellations of units) A weatherman carried an aneroid barometer from the ground floor to his office atop the Sears Tower in Chicago. On the level ground, the barometer reads 30.15in.Hg.A; topside reads 28.607in.Hg.A. The average atmospheric air density was 0.075 lb/cu.ft. Estimate the height of the building.

The previous Bartleby person that answered my questions BUT I dont understand were he got the answers from . I NEED HELP to replicate. I have ticked the parts I understood and been able to replicate. Given the table of results find the following. Give answers in KW. Please show all working out Rate of heat transfer to evaporator from the chilled water: Answer : 0.60KW ✓ Rate of heat transfer from condenser to the cooling water: Answer : 0.764KW ✓ Rate of heat transfer to refrigerant in “Evaporator” using enthalpy values: Answer: 1.5: I DON’T UNDERSTAND the answer given – see below Rate of heat transfer from refrigerant in “Condenser” using enthalpy values Work input from the compressor to the refrigerant using enthalpy values The previous Bartleby answer stated that at P1 =288 KPa and T1 =3.48 h1= 253.66 KJ/Kg P2 =823 KPa and T2 =65 h2= 301.48 KJ/Kg Given P3 =815 KPa and T3 =30.4 h3= 94.2 KJ/Kg (I don’t understand where the 94.2 comes from) P4 =294 KPa…
