Hot air flows through a pipe, as shown above. the properties of air may be taken as: k=0.03 w/m-k, pr=0.7, μ=208.2 x 10"n s/m^2 and ρ=0995 kg/m^3. calculate heat transfer coefficient between the inner surface of the pipe and the hot air.

Fluids at rest possess no flow energy. a)- true b)- false

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.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
