A sphere of specific gravity 7.8 is ropper into oil of specific gravity of .88 and viscoisty mu = 0.15 Pa-s. Esitmate the terminal velocity of the spehere if its dimaeter is (a) = 0.1 mm, (b) = 1.0 mm, and (c) = 10.0 mm.

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
