Abearing manufacturer has obtained five samples from a recent batch with diameters 2.50, 2.52, 2.53, 2.50 and 2.50 ? m. calculate the mean: d. i. 2.50 um ii. 2.53 um iii. 2.52um iv. 2.51 um

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
