Liquid water flows through a 2.0 cm diameter, 10.0 m long, smooth tube at a mass flow rate of 4.5 kg/s. The water enters the tube at 22EC, and the inner tube wall is maintained at 60EC. Find the outlet temperature of the water. (Use the Dittus-Boelter relation on pg. 496 of the text to find the heat transfer coefficient)

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
