A piston cylinder arrangement contains 0.02 m³ of air at 50°C and 400 kPa. Heat is added in the amount of 50 kJ and work is done by a paddle wheel until the temperature reaches 700°C. If the pressure is held constant, how much paddle-wheel work must be added to the air? Assume constant specific heats. Equations to be used: о - W раddle 3 т (hz — h) %3D тср (Тz — T1) PV m = RT

CO2 needs to be compressed from p1=1bar, t1=300k to p2=40bar to transport it to remote sites for sequestration. what is the minimum energy requirement per kg of CO2 for the compressor? Should the compressor operate adiabatically or isothermally for the best energy efficiency? The environment is at Tenv=300k. Use accurate thermodynamic data for CO2 in this problem.

I need help with this thermo practove problem that I do not understand- thank you! 2 kg of air in a piston cylinder initially at P1=101 kPa, T1= 300 K undergoes a cyclemade up of three processes: 1-2 Isothermal compression until the volume is (1/15) of its original value.2-3 Constant Pressure heating3-1 Isentropic Expansion back to the initial state Assume air is an ideal gas with constant specific heats with the following values: Cpo=1.027kJ/kgK; Cvo= 0.740 kJ/kgK; R=0.287 kJ/kgK; ɣ=1.388 Fill out the processes table below. Calculate Processes 1-2, 2-3, and 3-1 clearly
