1.Water at 15 C flows in a tube with an inside diameter of 50 mm.Determine the maximum value of average velocity for which the flow would be laminar.
2.A soil sample taken from a borrow pit has a natural void ratio of1.15. The soil will be used for a highway project where a total of 100,000 m3 of soil is needed in itscompacted state; its compacted void ratio is 0.73. How much volume has to be excavated from the borrow pit to meet thejob requirements.
