1. Give an application where it will be necessary to step up a voltage using a transformer. 2. A power utility pole has a transformer with 2400 turns in the primary and 4.5KV coming from the power line. Describe the center-tapped secondary needed to obtain 240V (120V/120V) for a commercial customer.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

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.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
