Consider the laminar flow of water in a circular pipe with diameter 90.00m and length 50.00mm. The density of water is 1000kgm3 and its dynamic viscosity at 20C is 1.000103kgm1s1 i. Calculate the Reynolds number, the volume flow rate, the pressure drop and the maximum velocity in the pipe for an average velocity equal to 1.200mms1. (4 marks) ii. Calculate the Reynolds number and the pressure drop that occurs in the pipe when the diameter is reduced by a factor of 10,100 and 1000 , if in all three cases the average velocity remains unchanged and equal to 1.200mms1. Compare the results and describe the effect of diameter change on pressure drop at the microand nanoscale
