Ahydraulic turbine has 85 m of elevation difference available at a flow rate of 0.25 m/s, and its overall turbine- generator efficiency is 91 percent. determine the electric power output of this turbine.

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.
