A cylinder-piston sistem contains CO2. The sistem
experiments an initial expansion where P1 = 20
lbf / in2 and V1 = 0.50
ft3 till the final state where P2= 5
lbf / in2 and V2= 2.50
ft3. The relation between pressure and volumen during
the process is P = A + BV, where A and B are constants.
a) For the CO2, evaluate the work done on ft /
lbf and Btu
b) Calculate the values of A and B in lbf / in2 and (lbf / in2 ) / ft3 respectively
If you make a conversion write it down please!!
The answers should be: a) 3600 ft / lbf or 4.63 Btu and
b) A= 23.75 lbf / in2 and B= -7.5
(lbf / in2 ) / ft3

A gas undergoes a process in a piston–cylinder assembly during which the pressure-specific volume relation is pv1.1 = constant. The mass of the gas is 0.4 lb and the following data are known: p1 = 160 lbf/in.2, V1 = 1 ft3, and p2 = 390 lbf/in.2 During the process, heat transfer from the gas is 2.1 Btu. Kinetic and potential energy effects are negligible. Determine the change in specific internal energy of the gas, in Btu/lb.
A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p1 = 60 lbf/in.and T1 = 90°F to a final state where P2 = 10 lbf/in. During the process, the pressure and specific volume are related by pr2 = constant. Determine the energy transfer by work, in Btu. W = Btu the tolerance is +/-2%
Argon is contained within a piston-cylinder assembly with initial state of V1 25 ft3 significant change in kinetic or potential energy, undergoes a thermodynamic cycle consisting of three processes as follows: Process 1-2: Adiabatic expansion with P aV + c, where c- 15 in Hg, a constant, and V2 40 ft3 p1 70 in Hg, and with no Process 2-3: Compression with pV-constant, U2 U3. Process 3-1: Constant-volume with AU-0.5 BTU 1. For process 1-2, find the constant a (with...
A piston-cylinder assembly contains air, initially at 60 lbf/in2, 900°R, and a volume of 0.05 ft3. The air undergoes a process to a state where the final volume is 0.10 ft3. The process is polytropic with n=1.4. Assuming ideal gas behavior for the air: a. Draw the process in the p-V diagram and write the engineering model. a. Clearly label the states and indicate the direction of the process. b. Determine the mass of the air, in lb
A gas contained within a piston-cylinder assembly undergoes two processes, A and B, between the same end states, 1 and 2, where p1=10 bar, V1= 0.1 m3, U1=400 kJ and p2=1 bar, V2=1.0 m3, U2=200 kJ: Process A. Process from 1 to 2 during which the pressure-volume relation is p.V = constant. Process B: Constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to state 2 Kinetic and potential energy effects can be ignored. For...
