Laminar flow normally persists on a smooth flat plate until a critical reynolds number value is reached. however, the flow can be tripped to a turbulent state by adding roughness to the leading edge of the plate. for a particularsituation, experimental results show that the local heat transfer coefficients for laminar and turbulent conditions are: hlam(x)= 1.74w/m^1.5. kx^-0.5hturb(x)= 3.98w/m^1.98. kx^-0.2 calculate the average heat transfer coefficients for laminar and turbulent conditions for plates of length l = 0.1 m and 1 m.

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.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
