1. Air at 70°F, Flows into a 10-ft3 reservoir at a velocity of 110 fps. If the reservoir pressure is 14 psig and the reservoir temperature 70°F, find the rate of temperature increase in the reservoir. Assume the incoming air is at reservoir pressure and flows through a 8-in.-diameter pipe.
2. Water flows through a 2-in.-diameter horizontal pipe at a flow rate of 35 gal/min. The heat transfer to the pipe can be neglected, and frictional forces result in a pressure drop of 10 psi. What is the temperature change of the water?
