Spring 2006 1 ME 201 Thermodynamics Homework #8 Due Wednesday, 2/15/06 1. Ten grams of water at 15 ° C and 100 kPa completely fills a balloon. The balloon is then heated on the stove top at constant pressure until the temperature reaches 125 ° C. Determine the boundary work in kJ involved in this process. What is the boundary power, if the process takes 700 seconds?

Unformatted text preview: 2. A piston-cylinder device of volume 0.05 ft 3 contains 0.001 lb m H 2 at 40 psia. The device undergoes a polytropic process with polytropic exponent 0.75 or PV 0.75 = constant which increases the pressure to 110 psia. . Determine (a) the boundary work in Btu for this process (b) the final temperature...
