Question: i got parts ae but how is f done...

Question details

HW 3 ME 361-Spring 2019 A handwritten accompaniment to EES is required for this problem. Sketch the problem setup by hand and show all your work (including all your math) by hand. Also print from EES See also the course policies and formatting information on Canvas for additional guidelines on what you should submit in this case 1 A cylindrical volume of air is contained in a piston-cylinder device. The device can be assumed to be ideal: perfect piston-cylinder seal, frictionless piston motion, etc. The cylinder axis is vertical, with the piston above the bottom of the cylinder. The cylinder has a 4 inch bore The initial height of the cylindrical air volume is h 1-3 inches. The initial temperature of the air is T1-212 °F. The initial pressure of the air is P 1-2.537 atm. The ambient pressure is 0962 atm a) Find the initial volume, V_1 [ft 3] b) Assuming the air pressure P1 is due to the ambient pressure added to the pressure exerted by the piston mass, find the initial mass of the piston [lbm] Next, starting from this condition, we will go to new conditions in various ways, one in each below. But in each part below, we are always starting from this same initial condition, state I c) The piston is locked in place with mechanical stops so that it cannot move. Then, the air d) The air is heated from state 1 by placing the cylinder in a kiln. The piston moves but its e) The cylinder is placed in a bath of boiling water that maintains its temperature at 212 °F is heated from state 1 by placing the cylinder in a kiln. It is heated until the pressure doubles. Find the work done by the piston on the surroundings, W c[BTU]. mass does not change. The heating continues until the airs volume doubles. Find the work done by the piston on the surroundings, W d [BTU] throughout the process. The mass of the piston is slowly reduced until the airs volume doubles. During this process, the air properties obey pV-constant (according to something vaguely familiar called the ideal gas law; we will study that law in detail soon). Find the work done by the piston on the surroundings, W e [BTU] f) The cylinder is insulated very well (assume perfectly, and the mass of the piston is slowly reduced until the airs volume doubles. During this process, the air properties obey pV14constant (according to material you will lean well when we get to chapter 6). Find the work done by the piston on the surroundings, W f[BTU
I got parts A-E but how is F done?
