A cylindrical specimen of undeformed brass that has a diameter of 300 mm is elastically deformed to a tensile strain of 0.001. If the Poisson’s ratio for this brass is 0.35, what is the change in specimen diameter?

Hydraulic fluid with a sg. of 0.78 is flowing through a 1.5 in. i.d. pipe at 58 gal/min. the fluid has an absolute viscosity of 11.8 x 105 lbf-sec/ft2. is the flow laminar, turbulent or within the critical range? give both a numerical reynolds number and a term answer.
