A 3-m-diameter, 7-m-long cylindrical tank is com- pletely filled with water. The tank is pulled by a truck on a level road with the 7-m-long axis being horizontal. Deter- mine the pressure difference between the front and back ends of the tank along a horizontal line when the truck (a) acceler- ates at 3 m/s2 and
(b) decelerates at 4 m/s2.

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.
