Air at 200 kpa enters a 2-m-long, thin-walled tube of 25-mm diameter at 150°c and 8 m/s. steam at 20 bars condenses on the outer surface. determine the outlet temperature and pressure drop of the air, as well as the rate of heat transfer to the air. evaluate the properties of air at tm=450 k

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
