A pistoncylinder device initially contains steam at 200 kPa, 2008C, and 0.4 m3 . At this state, a linear spring (F ~ x) is touching the piston but exerts no force on it. Heat is now slowly transferred to the steam, causing the pressure and the volume to rise to 250 kPa and 0.6 m3 , respectively. Show the process on a P-v diagram with respect to saturation lines and determine (a) the final temperature, (b) the work done by the steam, and (c) the total heat transferred.

Review of fluid mechanics Example problems Hydrostatic Pressure: example problem Hydrostatic Pressure: example problem Two chambers with the same fluid at their base are separated by a 30-cm-diameter piston whose weight is 25N. Calculate the gage pressures in chambers A and B. Hydrostatic Pressure: example problem Consider a hydraulic jack being used in a car repair shop. The pistons have an area of A = 0.8 cm and A = 0.04 m . Hydraulic oil with a specific gravity of 0.870 is pumped 1 2 in as the small piston on the left side is pushed up and down, slowly raising the larger piston on the right side. A car that weighs 13,000 N is to be jacked up. (a) At the beginning, when both pistons are at the same elevation (h = 0), ca
