A gas undergoes a process from state 1, where p1 = 60 lbf/in.2, v1 = 6.0 ft3/lb, to state 2 where p2 = 85.1 lbf/in.2, according to pv1.3 = constant. The relationship between pressure, specific volume, and internal energy is u = (0.2651)pv - 95.436 where p is in lbf/in.2, v is in ft3/lb, and u is in Btu/lb. The mass of gas is 10 lb. Neglecting kinetic and potential energy effects, determine the heat transfer, in Btu. Entry field...

A stream of liquid cyclopentane flows at a rate of 0.35 lbm / s into an initially empty container with a volume of 2.0 ft3, placed on a scale calibrated to read weight in lbf. The process takes place at sea level. When only the empty container was on the scale, the scale reading was 2.50 lbf. Estimate the reading 10 seconds after the flow starts. Answer is 6. I don't understand each step. Thank you!

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

Air within a piston–cylinder assembly, initially at 15 lbf/ in.2, 510°R, and a volume of 6 ft3, is compressed isentropically to a final volume of 3 ft3. Assuming the ideal gas model with k = 1.4 for the air, determine the: (a) mass, in lb. (b) final pressure, in lbf/in.2 (c) final temperature, in °R. (d) work, in Btu.
