Find roughness ε U= 2 m/s
D= 18 mm
v = 1.004 X 10-6 m2/s
p = 1000 kg/m3, g = 9.81 m/s2
0.80 m
0.47m
h1 = 1.15 m
h2 = 0.80 m
h3 =0.47 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
