A piston–cylinder device contains 50 kg of water at 250 kPa and 25°C. The cross-sectional area of the piston is 0.1 m2. Heat is now transferred to the water, causing part of it to evaporate and expand. When the volume reaches 0.26 m3, the piston reaches a linear spring whose spring constant is 100 kN/m. More heat is transferred to the water until the piston rises 20 cm more. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the final pressure and temperature. The final pressure is kPa. The final temperature is ºC. Find the work done during the process

A garden hose attached with a nozzle is used to fill a 20-gal bucket. The inner diameter of the hose is 1 in and it reduces to 0.53 in at the nozzle exit. The average velocity in the hose is 8 ft/s and the density of water is 62.4 lbm/ft3. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the volume and mass flow rates of water through the hose. The volume flow rate of water through the hose is ft3/s. The mass flow rate of water through the hose is lbm/s. The change in time? What is the exit velocity?

A 23-ft3 rigid tank initially contains saturated refrigerant-134a vapor at 160 psia. As a result of heat transfer from the refrigerant, the pressure drops to 50 psia. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the final temperature. Use data from refrigerant tables. The final temperature is ºF.
