A thick-walled, stainless steel (AISI 316) pipe of inside and outside diameters 25 mm and 40 mm is heated electrically to provide a uniform heat generation rate of 0.8 × 106 W/m3. The outer surface of the pipe is insulated, while water flows through the pipe at a rate of 0.1 kg/s. Evaluate the properties of the stainless steel (AISI 316) at 400 K. Assume the tube surface is smooth and use the Gnielinski correlation for the Nusselt number. (a) If the water inlet temperature is 20°C and the desired outlet temperature is 40°C, what is the required pipe length, in m?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
