A spring-loaded piston–cylinder device is initially filled with 0.13 lbm of an R-134a liquid–vapor mixture whose temperature is 230°F and whose quality is 80 percent. The spring constant in the spring force relation F 5 kx is 37 lbf/in, and the piston diameter is 12 in. The R-134a undergoes a process that increases its volume by 50 percent. Calculate the final temperature and enthalpy of the R-134a

Consider airflow over a flat plate of length l = 1.5 m under conditions for which transition occurs at le = 0.9 m based on the critical reynolds number, re, e = 5 x 10. evaluating the thermophysical properties of air at 400 k, determine the air velocity. (hint: use the tables to find the properties of air)
