Heat transfer homework 5 2018-2019 fall problem 1 air at 1.01325x105 bar and a temperature of 300 c flows with a velocity of 2 m/s over a flat plate 0.5 m long. estimate the cooling rate per unit width of the plate needed to maintain it at a surface temperature of 27 c. air t = 300°c m_ 2 m/s - rt, -27°c l = 0.5 m

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
