A plate separated by 0.5mm from a fixed plate moves at 0.5 m/s under a shear stress of 4.0 N/m2. Determine the viscosity of the fluid between the plates​

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
