For laminar flow over a flat plate, the local heat transfer coefficient, hx, is known to vary as varies as x^1/3, where x is the distance from the leading edge (x=0) of the plate. What is the ratio of the average heat transfer coefficient between the leading edge and the location x on the plate to the local heat transfer coefficient at x?

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

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

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
